Hyperpolarized 13C-Pyruvate Imaging for Pancreatic Cysts
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new imaging method to help doctors distinguish between harmless and dangerous pancreatic cysts. The imaging uses hyperpolarized C-Pyruvate, a special substance injected during an MRI scan to provide clearer pictures of the cysts. It targets individuals with pancreatic cysts who plan to undergo surgery or a biopsy. Participants must understand and sign a consent form and have no conditions that prevent safe MRI use. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this innovative imaging method.
Do I need to stop my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that Hyperpolarized 13C-Pyruvate Magnetic Resonance Spectroscopic Imaging is safe?
Research shows that a new imaging technique, hyperpolarized 13C-pyruvate MRI, is being tested for safety and effectiveness in detecting pancreatic cysts. In earlier studies, patients generally handled the procedure well, and no serious side effects occurred.
The process involves injecting a special substance, 13C-pyruvate, into a vein and then using an MRI machine to take pictures. This method is noninvasive, meaning it doesn't require surgery. Researchers closely monitor patients during the procedure to ensure their safety.
As a phase 1 study, the main goal is to assess safety and determine the right dose. If a treatment successfully passes this stage, it is usually considered safe enough for further testing. However, because this is an early phase, all safety details are not yet fully understood.12345Why are researchers excited about this trial?
Researchers are excited about hyperpolarized 13C-pyruvate magnetic resonance spectroscopic imaging because it offers a brand-new way to visualize pancreatic cysts. Unlike traditional imaging techniques, this method uses hyperpolarized 13C-pyruvate as a contrast agent to provide incredibly detailed images, potentially allowing doctors to better assess the nature of these cysts. This innovative approach could lead to more accurate diagnoses and improved treatment plans without the need for invasive procedures. Plus, the imaging process is quick, taking just a few minutes, which is a significant advantage over some existing diagnostic methods.
What evidence suggests that Hyperpolarized 13C-Pyruvate Imaging is effective for detecting pancreatic cysts?
Research has shown that a special imaging technique called Hyperpolarized 13C-Pyruvate Magnetic Resonance Spectroscopic Imaging (HP-MR), which participants in this trial will undergo, might help doctors determine if pancreatic cysts are non-cancerous or cancerous. This technique examines how pyruvate, a natural substance in the body, is used in tissues. Studies have found that cancerous cells often convert pyruvate into another substance called lactate more than normal cells do. By highlighting these changes, HP-MR could provide clearer information about the cysts. Early evidence suggests this method might offer a noninvasive way to assist with diagnosis and treatment decisions.12567

Experimental Treatment
Participants will have the HP-MR scan within the 4 weeks before your scheduled surgery. Hyperpolarized C-Pyruvate will be injected by vein during the scan. Your vital signs (temperature, blood pressure, heart rate and respiration \[breathing\]) will be monitored during the scan. The estimated time of the scan is a couple of minutes, but you may be in the room of the MRI for up to 30 minutes for preparation. The entire process of obtaining the MRI (and possible blood draw) may be up to half of a work day (not including your personal travel time).
