This study focuses on male and female patients being treated for breast cancer that is positive for the HER2 receptor which requires special treatments targeting that receptor. The problem is that these treatments, while effective for the cancer, can sometimes harm the heart. Because of this, patients have to undergo heart tests every three months during treatment, even if they have no history of heart disease or feel fine.
The guidelines for these regular heart tests were established decades ago when these treatments were first introduced, but research shows that most of these tests don't actually change the treatment plan. This suggests that many patients are going through unnecessary tests, which can cause stress, delay treatments, and increase healthcare costs.
To address this, the researchers propose a new study with 300 patients with HER2 positive breast cancer to test a more personalized approach to cardiac surveillance. Participants will be classified based on their risk of heart problems: low or intermediate. Instead of testing every patient every three months, those in the intermediate group will be tested every 4 months, and those in the low-risk group will be tested every 6 months. The researchers will compare this new approach to the current system to see if fewer tests are just as safe and effective.
The researchers will measure heart health, how well cancer treatments are completed, and how patients feel about having fewer tests. If this new approach works, it could save money and reduce the burden on female patients without risking their health.

MR Spectroscopy for Brain Tumor
Bethesda, Maryland
Background:
Glioma is a type of brain cancer. Some of these tumors have gene mutations. These mutations can cause a substance called 2-HG to build up in the brain. This makes the tumors more aggressive. Researchers want to better understand 2-HG buildup in the brain. They hope this can help them design better ways to test for gliomas.
Objective:
To monitor the level of 2-HG in the brains of people with gliomas that have mutations in the IDH1 or IDH2 genes.
Eligibility:
People ages 18 and older with gliomas with mutations in the IDH1 or IDH2 genes
Design:
Participants will be screened with:
Medical and cancer history
Physical exam
Reviews of their symptoms and ability to perform normal activities
Blood and urine tests
MRI scan
Samples of their tumor from a past surgery
Documentation of their diagnosis and mutation status
Participants will have an initial evaluation. This will include repeats of screening tests. It will also include:
Neurological exam
MRS and MRI scans of the brain: Participants will lie on a table that slides into a metal cylinder. A coil or soft padding will be placed around their head. They will have a contrast agent injected into a vein. Pictures will be taken of the brain.

A particular MRI method called magnetic resonance spectroscopy (MRS) can be used to study brain chemistry as well, which may help researchers who are studying new treatments for psychiatric illnesses. Researchers are interested in improving current MRI and MRS techniques, as well as developing new MRI and MRS techniques to view and measure brain chemicals and brain activity.
Objectives:
- To implement, develop, and optimize brain chemistry imaging techniques using magnetic resonance imaging and magnetic resonance spectroscopy.
Eligibility:
- Healthy individuals between 18 and 65 years of age.
Design:
* This study will involve a screening visit and a scanning visit at the National Institutes of Health Clinical Center.
* Participants will be screened with a full medical and physical examination, blood and urine tests, and neurological testing.
* During the second visit, participants will have an MRI scan of the brain. (Participants who have received an MRI within the past year will not need to have a second one; the images of the previous scan will be used for this study.)

Radioactive Tracer for Multiple Sclerosis
Bethesda, Maryland
Background:
Multiple sclerosis (MS) and progressive multifocal leukoencephalopathy (PML) are disorders that affect the central nervous system (CNS). The CNS includes the brain, spinal cord, and optic nerves. Both diseases can cause muscle weakness and impair vision, speech, and coordination. Researchers are working to better understand how MS and PML affect the CNS.
Objective: To test whether an experimental radioactive tracer (minibody) can help positron emission tomography (PET) scans detect certain immune cells in the CNS of people with MS and PML.
Eligibility:
People aged 18 years and older with MS or PML.
Design:
Participants will come to the clinic for at least 3 visits over 4 to 6 weeks.
Participants will undergo testing. They will have a physical and neurological exam. They will have blood tests and tests of their heart function. They will have a magnetic resonance imaging (MRI) scan of the brain. They may have a spinal tap: Their lower back will be numbed, and a needle will be inserted between the bones of the spine to withdraw fluid from around the spinal cord.
Minibody is given through a tube with a needle placed in a vein in the arm. This takes 5 to 10 minutes. Participants will have heart function tests before and after receiving the minibody.
Participants will return the next day for the PET scan. They will lie on a table that moves through a doughnut-shaped machine. This scan will take about 1 hour.
Participants with PML may opt to repeat the minibody infusion and the PET scan within 6 months.

Transcranial Magnetic Stimulation for Depression
Bethesda, Maryland
Background:
Major depressive disorder (MDD) is one of the most impairing medical conditions in the world. Medication and some kinds of talk therapy are standard treatments for teens with MDD, but these do not work well for everyone. Transcranial magnetic stimulation (TMS) has been approved to treat MDD in adults. TMS might help adolescents, too.
Objective:
To test TMS combined with cognitive behavioral therapy (CBT) in teens with MDD.
Eligibility:
People aged 13 to 17 years with MDD that has not responded to treatment.
Design:
Participants will be screened. They will have a physical exam and psychiatric evaluation. They will have an MRI scan and a test of their heart function. They will enroll in 2 NIH protocols (01-M-0254 and 18-M-0037).
For 2 to 6 weeks, participants will have weekly CBT, a kind of talk therapy. They will taper off of their psychiatric medicines.
For 2 weeks, participants will come to the clinic every weekday. They will receive 3 or 4 sessions of TMS on each of those days. A wire coil will be held on their scalp. A brief electrical current in the coil creates a magnetic pulse that affects brain activity. They will receive 30 TMS pulses in 10-second bursts; these will be repeated 60 times in each 15-minute session. Participants may hear a click and feel a pulling sensation under the coil. They may feel their muscles twitch. Each day, they will have tests of concentration, thinking, and memory. Some may have a 3rd week of TMS.
Participants will remain in the study for 5 more weeks. They will begin taking their medications again.

[18F]FAPI-74 PET Imaging for Cancer Detection
Bethesda, Maryland
Background:
Fibroblast-activation protein (FAP) is an enzyme that appears in high numbers in certain cancer cells. \[18F\]FAPI-74 is a new tracer-a substance that is injected into a person s body before an imaging scan. Researchers believe that \[18F\]FAPI-74 may be able to highlight FAP enzymes more effectively than approved tracers. If so, the new tracer would make it easier to find FAP-positive tumors in the body.
Objective:
To see if \[18F\]FAPI-74 PET scans are as good or better than other methods for detecting certain cancers.
Eligibility:
People aged 18 years or older with cancer in 1 of these places: the ducts of the pancreas, liver, gallbladder, or small intestine; stomach; bladder; ovaries; or adrenal glands. They must be enrolled in an NIH treatment study for their cancer.
Design:
Participants will have 2 baseline scans: 1 with \[18F\]FAPI-74; 1 with an approved tracer.
The \[18F\]FAPI-74 will be infused through a tube attached to a needle inserted into a vein. About 1 hour later, the participant will undergo 1 or more imaging scans.
Within 1 week, participants will undergo the same scanning procedures with the approved tracer.
If the baseline scan with \[18F\]FAPI-74 shows the tumors, scans with this tracer will be repeated when their regular treatment regimen calls for scans again. If the scans with the regular tracer also showed tumors, this scan will be repeated within the same week as the repeated \[18F\]FAPI-74 scans. If either type of scan showed no tumors, that scan will not be repeated.
If the participant's cancer progresses within 2 years, both types of scan may be repeated.
Follow-up calls will continue for 2 years.

PET Imaging for Alcoholism
Bethesda, Maryland
Background:
People with alcohol use disorder (AUD) also often have bouts of depression called major depressive episodes (MDEs). People having MDEs have been found to have low levels of a protein called PDE4B in the brain. Researchers want to find out if people with AUD also have low levels of PDE4B. This research may help lead to better treatments for AUD.
Objective:
To find out (1) if PDE4B levels are lower in people who are withdrawing from AUD and (2) if their PDE4B levels go up after they abstain from alcohol for 3 to 4 weeks.
Eligibility:
Adults aged 18 to 70 years with AUD. They must be enrolled in protocol 14-AA-0181.
Design:
Participants enrolled in protocol 14-AA-0181 will stay in the clinic for 3 to 4 weeks for alcohol withdrawal. During this stay, they will have some added procedures for the current study.
Within the first week, participants will have a positron emission tomography (PET) scan of the brain. A needle will be used to guide a thin plastic tube (catheter) into a vein in one arm. An experimental substance called a radioactive tracer will be injected through the catheter. This tracer binds to PDE4B and makes it easier to see the protein in the brain. For the scan, participants will lie on a table that slides into a doughnut-shaped machine.
Participants will have a second PET scan toward the end of their stay in the clinic.
Participants may also have a magnetic resonance imaging (MRI) scan of the brain. They will lie on a bed that slides into a tube....

Fluoxetine for Anxiety and Depression
Bethesda, Maryland
Study Description:
This study examines relations between neurocognitive and clinical features of pediatric anxiety disorders. The study uses neuro-cognitive tasks, functional magnetic resonance imaging (fMRI), as well as magneto- and electro-encephalography (M/EEG). Patients will be studied over one year, before and after receiving either one of two standard-of-care treatments: cognitive behavioral therapy (CBT) or fluoxetine, a serotonin reuptake inhibitor (SSRI). Healthy comparisons will be studied at comparable time points.
Primary Objectives:
To compare healthy youth and symptomatic, medication-free pediatric patients studied prior to receipt of treatment. The study seeks to detect relations between clinical features of anxiety disorders at baseline and a wide range of neurocognitive features associated with attention, memory, and response to motivational stimuli.
Secondary Objectives:
1. To document relations between baseline neurocognitive features and response to Cognitive Behavioral Therapy (CBT) or fluoxetine, as defined by the Pediatric Anxiety Rating Scale (PARS) and Clinical Global Improvement (CGI) Scale.
2. To document relations between post-treatment changes in neurocognitive features and anxiety symptoms on the PARS following treatment with Cognitive Behavioral Therapy (CBT) or fluoxetine.
3. To document relations among broad arrays of clinical, cognitive, and neural measures
Primary Endpoints:
Indices of percent-signal change in hypothesized brain regions, comprising amygdala, striatum, and prefrontal cortex (PFC) for each fMRI and MEG paradigm.
Secondary Endpoints:
1. Treatment-response as defined by a continuous measure, the Pediatric Anxiety Rating Scale score (PARS), and a categorial measure, the Clinical Global Improvement (CGI) score.
2. Levels of symptoms and behaviors evoked by tasks that engage attention, memory, and elicit responses to motivational stimuli.

Rehabilitation Methods for Stroke Recovery
Toronto, Ontario
The goal of this clinical trial is to compare two rehabilitation methods to improve finger movements in people who have had a stroke. The main question it aims to answer is which of these two training methods leads to the most improvement:
1. Teaching people to reach their movement goals using any strategies they like.
2. Teaching people to improve their movement technique and avoid compensatory strategies.
There is no one-size-fits-all approach. The second goal is to find out who might benefit more from each method. Some people with stroke may rely on compensatory strategies due to severe impairment, while others with milder strokes might benefit more from techniques that enhance movement quality.
The third goal is to take pictures of the brain to see how it changes with each method. This will help researchers understand how the brain adapts after a stroke and could lead to treatments that target the brain directly.
Participants will:
1. Visit the lab for clinical and research assessments on weeks 1, 4, 5, and 15.
2. Complete 10 days of piano training.
3. Undergo magnetic resonance imaging (MRI) scans twice, once in week 1 and once in week 4.

Objectives:
To study what happens in the brains of people who drink alcohol when they look at pictures of social things and of alcohol. To learn if people can control brain activity in a magnetic resonance imaging (MRI) scanner and if this helps people with drinking.
Eligibility:
Adults ages 21 65 who have an alcohol use disorder.
Healthy volunteers ages 21 65
Design:
Participants will be screened with
Physical exam
Medical history
Blood, urine, and heart tests
Mental health interview
Questions about their alcohol drinking.
At each session, participants will have:
A urine test for drugs and pregnancy. If they test positive, they cannot participate.
A breath alcohol test and assessment for alcohol withdrawal.
Participants will complete surveys, talk to researchers about behaviors, and play games.
Participants will have MRI brain scans. The scanner is a metal cylinder in a strong magnetic field. They will lie on a table that slides in and out of the scanner for 1 2 hours.
Participants will do tasks in the scanner:
They will look at pictures, sometimes of alcohol.

Improved Heart MRI Techniques for Heart Disease
Bethesda, Maryland
Background:
- Imaging tests, such as magnetic resonance imaging (MRI), can provide information about heart and blood vessels. The tests let doctors can see the amount of blood vessel narrowing and vessel wall thickness. This information may help diagnose and treat heart disease and other conditions that lead to heart attacks. Better MRI methods are needed to improve heart disease diagnosis, especially by avoiding the use of radiation. Researchers are testing new techniques to improve the quality of heart MRI, compared with more complex studies like catheterization or angiography.
Objectives:
- To compare heart MRI techniques with other tests used to diagnose heart disease.
Eligibility:
- People at least 18 years of age who either have or may have heart disease, or are healthy volunteers.
Design:
* Participants will be screened with a physical exam, medical history, and blood tests.
* They will have an angiography to study the inside of blood vessels. This test is an x-ray study of the blood vessels. It will be done either separately or as part of a set of tests to diagnose possible heart disease.
* Participants will have at least one and up to five MRI scans. The scans will involve different methods of studying the heart and blood vessels. Participants may also have a computed tomography scan to confirm the findings of an MRI scan.
* No treatment will be provided as part of this protocol.

Psychological Interventions for Pain Perception
Bethesda, Maryland
Background:
- Painful stimuli cause changes in a network of brain regions called the "Pain Matrix." But most of these regions respond to many other stimuli, not just pain. Researchers want to understand how different factors influence pain. They want to test what happens when people expect different levels of pain and receive treatments that can modify pain. They want to see if these factors influence decisions about pain and how the body responds to it. They also want to compare pain with responses like taste and vision.
Objectives:
- To better understand how pain and emotions are processed and influenced by psychological factors.
Eligibility:
- Healthy volunteers ages 18-50.
Design:
* This study requires 1 to 2 clinic visits that last 1 to 3 hours.
* Participants will be screened with medical history and physical exam.
* Some participants will have one or more magnetic resonance imaging (MRI) scans of their brain. For MRI, participants will lie on a table that slides in and out of a cylinder. The scanner makes loud knocking noises. They will get earplugs.
* Participants heart activity will be recorded with electrocardiogram. Their pulse, sweating, and breathing will be monitored.
* Some participants will take a taste test. Others may perform simple tasks. Others may receive pain in their arm, leg, or hand. The pain will come from heat or electric shocks. Others may judge pain using a topical pain-relieving cream. Some of these tests may be given during MRI.
* Participants will fill out questionnaires.
* The study will last 3 years.

18F-Fluciclovine PET/CT Scan for Multiple Myeloma
Bethesda, Maryland
Background:
Multiple myeloma (MM) is an incurable cancer of certain blood cells. MM often returns after treatment, and most people survive only 5 to 8 years after diagnosis. To improve survival, researchers need to find ways to identify returning disease earlier.
Objective:
To find out if the radiotracer 18F-fluciclovine (a substance injected into the blood during imaging scans) is better at detecting MM than the one (18F-FDG) currently used for this purpose.
Eligibility:
Adults aged 18 years or older with MM. The MM may be newly diagnosed (NDMM); or it may have returned or failed to respond after at least 1 prior line of treatment (RRMM).
Design:
Participants will be screened. They will have blood tests. They will have a positron emission tomography (PET) or computed tomography (CT) scan using 18F-FDG. The radiotracer will be injected into a vein. Then participants will lie on a table while the PET/CT scan takes images of their body.
All participants will have 3 study visits. During each visit they will have:
Two PET/CT scans. One with 18F-FDG, one with 18F-fluciclovine.
An optional magnetic resonance imaging scan.
A bone marrow biopsy. An area on the hip will be numbed; a needle will be inserted to draw out a sample of the soft tissue from inside the bone.
These tests may be spread over 30 days for each visit.
NDMM participants will have their second study visit 2 to 4 weeks after they complete their usual treatment for the disease. RRMM participants will have their second visit 6 months after their first.
All participants will have a third study visit after 5 years or when their disease progresses.

HNK for Treatment-Resistant Depression
Bethesda, Maryland
Background:
Major depressive disorder (MDD) is a serious mental illness that can put people at risk of self-harm and death. Many drugs are used to treat MDD, but it can take a long time for them to be effective. Researchers want to know if a faster-acting drug, (2R,6R)-hydroxynorketamine (HNK), can better treat the symptoms of MDD.
Objective:
To test a study drug (HNK) in people with MDD.
Eligibility:
People aged 18 to 70 years with MDD. They must have had a screening assessment under protocol 01-M-0254.
Design:
Participants will be tapered off their current MDD drugs over 2 to 5 weeks. They will stay off of the drugs for up to 2 weeks prior to starting the study medication and procedures. They will have a physical exam with blood tests. They will have tests of their heart function, mood, and thinking. They will answer questions about their symptoms. They may choose to have imaging scans and scans of their brain activity.
HNK is given through a tube attached to a needle inserted into a vein. Participants will receive infusions on this schedule:
They will receive 4 infusions over 2 weeks. They will stay in the clinical center overnight after each infusion or for the duration of the study.
They will receive no drugs for 2 to 3 weeks.
They will have 4 more infusions over 2 weeks, with overnight stays after each or for the duration of the study.
One set of 4 infusions will be the HNK. The other set of 4 infusions will be a placebo. A placebo looks just like the real drug but contains no medicine. Participants will not know when they are getting the HNK or placebo.

Why Other Patients Applied
"I have dealt with voice and vocal fold issues related to paralysis for over 12 years. This problem has negatively impacted virtually every facet of my life. I am an otherwise healthy 48 year old married father of 3 living. My youngest daughter is 12 and has never heard my real voice. I am now having breathing issues related to the paralysis as well as trouble swallowing some liquids. In my research I have seen some recent trials focused on helping people like me."

"I was diagnosed with stage 4 pancreatic cancer three months ago, metastatic to my liver, and I have been receiving and responding well to chemotherapy. My blood work revealed that my tumor markers have gone from 2600 in the beginning to 173 as of now, even with the delay in treatment, they are not going up. CT Scans reveal they have been shrinking as well. However, chemo is seriously deteriorating my body. I have 4 more treatments to go in this 12 treatment cycle. I am just interested in learning about my other options, if any are available to me."

Neuroimaging for Chronic Fatigue Syndrome
Bethesda, Maryland
Background:
The way the brain processes rewards and punishments may play a role in some disorders of the nervous system. People with chronic overlapping pain conditions (such as myalgic encephalomyelitis/chronic fatigue syndrome \[ME/CFS\]) may have heightened responses to unpleasant, punishing sensations. Some of these conditions may also cause heightened responses to effort; this is an unpleasant sensation felt during physical and mental exertion.
Objective:
To learn more about how the brain processes different unpleasant sensations.
Eligibility:
People aged 18 to 50 years with ME/CFS. Healthy volunteers are also needed.
Design:
Participants will have 3 visits in 1 to 5 weeks.
Visit 1: Participants may have a neurologic exam. They will have a mock magnetic resonance imaging (MRI) scan. They will lie on a bed in a wooden tube while they practice 2 tasks:
Thermal pain rating: A device that creates mild to moderate heat will be placed on one leg.
Physical effort rating: Participants will squeeze a plastic bar with different levels of force.
Visit 2: Participants will have a real MRI scan. They will lie on a table that slides into a large tube.
Visit 3: Participants will have another MRI scan. They will repeat the thermal pain and physical effort tasks while in the scanner. Sensors will be placed on 1 arm to measure how the muscles function as they squeeze the bar.
Their heart rate will be tested: They will hold their finger against a camera lens for 1 minute. They will do 2 other tasks: 1 requires repeatedly pressing a key on a keyboard, and the other requires squeezing a bar.

Nutrition Fortification for Preterm Infants
Washington, District of Columbia
Human milk has several well-established benefits but does not adequately meet the increased nutritional demands of the growing preterm infant, necessitating additional nutrient supplementation in a process known as fortification. In U.S. neonatal intensive care units (NICUs), human milk is primarily supplemented using standardized fortification, in which a multicomponent fortifier is added to human milk to achieve assumed nutrient content based on standard milk reference values. However, this method does not account for the significant variability in human milk composition or in preterm infant metabolism, and up to half of all very premature infants experience poor growth and malnutrition using current nutritional practices. Poor postnatal growth has adverse implications for the developing preterm brain and long-term neurodevelopment.
Recent advances allow for individualized methods of human milk fortification, including adjustable and targeted fortification. Adjustable fortification uses laboratory markers of protein metabolism (BUN level) to estimate an infant's protein requirements. In targeted fortification, a milk sample is analyzed to determine its specific macronutrient and energy content, with additional macronutrient supplementation provided as needed to achieve goal values. Emerging data suggest that both methods are safe and effective for improving growth, however information on their comparable efficacy and neurodevelopmental implications are lacking, particularly using advanced quantitative brain MRI (qMRI) techniques.
Through this prospective, randomized-controlled trial, the investigators will compare the impact of individualized human milk fortification on somatic growth and neurodevelopment in preterm infants. Infants will be randomized to receive one of three nutritional interventions: standardized (control group), adjustable, or targeted human milk fortification. Infants will undergo their assigned nutritional intervention until term-equivalent age or discharge home, whichever is achieved first. Brain qMRI will be performed at term-corrected age, and neurodevelopmental follow-up will be performed through 5 years of age.

Neuropharmacological Imaging for Addiction
Washington, District of Columbia
Background:
- Functional and structural magnetic resonance imaging (MRI) techniques have allowed researchers to map and study how the brain works when at rest and when engaged in specific tasks. MRI scans have provided more information about how drugs affect the brain, and about how drug addiction changes the brain and influences behavior, mood, and thinking processes. To better understand the underlying mechanism of drug addiction and to develop strategies for more effective treatment, researchers are interested in developing new MRI techniques to study the effects of addiction on the brain.
Objectives:
- To develop new functional and structural MRI techniques, and to evaluate their potential use in brain imaging studies related to addiction.
Eligibility:
* Individuals between 18 and 80 years of age.
* Participants may be smokers or nonsmokers, and may use drugs or not use drugs.
Design:
* During the initial screening, participants will complete questionnaires about family and personal history, drug use, and other information as required by the researchers. Participants who will be asked to complete tasks during the MRI scan will be shown how to perform these tasks before the scanning session.
* Before each study session, participants may be asked to complete some or all of the following: questions about their drug use during the last week, a breathalyzer test, a urine drug-use assessment, a urine pregnancy test, or a measure of carbon monoxide. Participants will also provide blood samples before the start of the scan.
* For each scanning session, participants will have an MRI scan that will last approximately 2 hours.
* MRI scans may include specific tasks to be performed during the scan, or an experiment that studies the brain's response to carbon dioxide....

Focused Ultrasound for Tobacco Use Disorder
Washington, District of Columbia
The goal of this clinical trial is to to inhibit the dorsal anterior insula (dAI) with low intensity focused ultrasound (LIFU) to determine the causal role for the dAI in smoking cue induced craving in individuals with tobacco use disorder (TUD); smoking cue induced craving is a clinically important behavior which has been associated with the severity of nicotine addiction. The main question\[s\] it aims to answer are:
* the safety and tolerability of dAI LIFU compared to sham stimulation in individuals with TUD
* the effects of LIFU vs sham to left dAI functional magnetic resonance imaging (fMRI) BOLD activity and craving in response to smoking cue exposure.
Participants will undergo anatomical MRI, neurological assessment, clinical assessment and patient query to assess the safety and tolerability of LIFU vs sham.
Participants will undergo functional magnetic resonance imaging where we will measure the effect of LIFU vs sham on 1) dAI blood-oxygen-level-dependent (BOLD) activation in response to smoking (compared to neutral) cue exposure and 2) cue-induced craving in individuals with TUD. Each participant will receive LIFU and sham stimulation.

Low Intensity Focused Ultrasound for Chronic Pain
Washington, District of Columbia
In this study, the research team will use low-intensity focused ultrasound (LIFU) to temporarily change brain activity in a brain region that is known to be involved in chronic pain. Through this, the research team hopes to learn about how the brain area works in response to pain. There are main questions this study aims to answer:
* The effect of LIFU to inhibit the posterior region of the insula (PI) compared to sham stimulation in individuals with chronic back pain (CBP) and widespread pain symptoms.
* The effect of LIFU to PI compared to sham stimulation to reduce pain intensity and magnitude of the Neurologic Pain Signature (NPS) in response to evoked thermal pain.
* The effect of LIFU to PI compared to sham stimulation to reduce pain intensity and magnitude of Tonic Pain Signature in response to tonic pain.

Fluorescence Imaging for Breast Cancer
Milwaukee, Wisconsin
Breast conserving surgery (BCS) is performed on patients with breast cancer to resect and completely remove the cancer while conserving as much of the surrounding healthy tissue as possible. Current methods do not allow surgeons to determine the completeness of surgical resection in real-time. This often results in the need for a second surgical procedure, or in some cases more than two surgical procedures in order to have confidence that all cancer has been removed.
This Phase 3 study will evaluate the safety and efficacy of the fluorescent imaging agent PD G 506 A for the real-time visualization of cancer during standard of care breast conserving surgery. PD G 506 A is an investigational drug which is converted in the body into a fluorescent molecule that accumulates in cancer cells. Patients receiving PD G 506 A will undergo standard of care breast conserving surgery followed by fluorescence imaging and removal of any potentially cancerous tissue left behind in the surgical cavity.

High-Resolution PET-CT Imaging for Cancer
Nashville, Tennessee
Imaging will be exploratory and be used intraoperatively. There have been no discovered risks associated with the device to be used in this study, and none are anticipated given the diagnostic and non-invasive, 'ex vivo' nature of device use. Of note, the surgical resection will proceed as per standard of care and will not be affected by the research protocol.
Potential Benefit: Imaging intra-operatively will ensure surgeons to identify at risk resection margins.
Time Commitment: There are no additional visits that will be asked of you to partake in this study.
Drug is FDA approved and Exposure to Radiation is minimal.

MRI Safety for Pacemaker and Defibrillator Patients
Baltimore, Maryland
Ferromagnetic Implants such as permanent pacemakers (PPM's) and Implantable Cardioverter Defibrillators (ICD's) have traditionally been accepted as contraindications to Magnetic Resonance Imaging (MRI) due to safety concerns. Over the past several years, MRI safety has been established in patients with pacemakers or ICD's but only in patients in whom strict vetting procedures were implemented. These vetting procedures were initially developed to eliminate devices, leads and device/lead circumstances thought to carry increased risk. Over recent years however, objective scientific evidence has failed to support this concern raising the question as to whether or not these vetting procedures are necessary.
Investigators hypothesize that in view of the existing objective scientific data, evolution of device technology and the fact that the investigators have scanned more than 2,000 devices safely (RPN03-08-11-12 and 00051707) ICD's and pacemakers and device circumstances previously excluded from MRI protocols can be safely scanned without prior vetting.
This is a prospective, non randomized, cohort study. Seventeen Hundred participants with an implanted ICD or pacemaker and a clinical need for MRI will be included in the study. Unlike previous studies where strict vetting procedures were implemented pre-procedure, All patients with a pacemaker or ICD and clinical need for an MRI will be eligible for inclusion in the study provided participants meet standard MRI inclusion/exclusion safety criteria.

HP Pyruvate MRI for Cancer Detection
Baltimore, Maryland
Many human diseases are characterized by their ability to alter existing metabolic pathways and interrupt cellular processes. Cancer exploits the Warburg effect and utilizes greater glucose than normal cells and within this process uses anaerobic respiration, leading to increased conversion of pyruvate to lactate. This can be exploited by hyperpolarized imaging. Hyperpolarized 13C MRI imaging is an approach that utilizes a stable isotope of Carbon (13C) linked to pyruvate. MRI spectroscopy is used in conjunction with hyperpolarized 13C pyruvate in order to temporally detect pyruvate and its conversion to lactate in-vivo, in order to visualize downstream metabolic (glycolytic) activity secondary to the Warburg effect, which should be useful in detecting and characterizing tumors of various types. Hyperpolarized 13C pyruvate MR imaging has not been tested in most cancers. In this preliminary survey, we will test the hypothesis that hyperpolarized 13C pyruvate MR imaging can be used to image various cancers.

Frequently Asked Questions
How much do Imaging clinical trials pay?
Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.
How do Imaging clinical trials work?
After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across Imaging trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length for Imaging is 12 months.
How do I participate in a study as a "healthy volunteer"?
Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.
What does the "phase" of a clinical trial mean?
The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.
Do I need to be insured to participate in a Imaging medical study?
Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.
What are the newest Imaging clinical trials?
Most recently, we added [18F]FAPI-74 PET Imaging for Cancer Detection, Radiotherapy Techniques for Oropharyngeal Cancer and Brain Stimulation for Stuttering to the Power online platform.
