What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to test new MRI devices not yet approved for regular use, seeking to enhance the performance of MRIs, which are imaging machines that capture internal body images. The trial seeks healthy volunteers to undergo MRI scans at GE Healthcare in Aurora. Those in good health and interested in advancing medical technology might be suitable for this study. As an unphased study, this trial offers participants the chance to contribute to the development of cutting-edge medical imaging technology.

Do I need to stop my current medications for the MRI study?

The protocol does not specify whether you need to stop taking your current medications for this study.

What prior data suggests that these MRI devices are safe for use in humans?

Research has shown that MRI (Magnetic Resonance Imaging) is generally safe, even for some individuals with pacemakers or defibrillators. A large study found low risks when using MRI on patients with these devices, provided safety guidelines are followed. Another study suggested that MRI can be safe for people with certain heart devices, but caution is necessary.

MRI uses strong magnets to capture images of the body. While these magnets may pose concerns for individuals with certain implanted devices, healthy volunteers without such devices typically do not face these risks.

Overall, MRI technology is well-researched and widely used in hospitals. However, since the MRI machines in this study are experimental, caution remains essential. Participants should ensure they understand the potential risks and ask questions if needed. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about this trial because it explores the safety and efficacy of performing MRI scans on patients with pacemakers (PPMs) or implantable cardioverter-defibrillators (ICDs). Traditionally, MRIs have been avoided in these patients due to concerns about device interference. However, this study aims to demonstrate that MRIs can be safely conducted with these devices, which could significantly expand diagnostic options for patients who need precise imaging without compromising their cardiac device function. This has the potential to improve patient care by providing more comprehensive diagnostic information.

What evidence suggests that this MRI device is effective for imaging?

Studies have shown that MRI (magnetic resonance imaging) is generally safe, even for individuals with certain heart devices like pacemakers and implantable cardioverter-defibrillators (ICDs). Research confirms that MRI can be safely performed on patients with newer "MRI-conditional" ICDs, designed to function with MRI machines. A large study found that a specific MRI method was safe for patients with older pacemakers and ICDs. This trial will include patients with a PPM or ICD undergoing a clinically indicated MRI. These findings demonstrate that careful use of MRI can be safe and effective for imaging, even for those with certain heart devices. ^{1 4 6 7 8}

Published Research Related to This Trial

Gadopentetate dimeglumine (Gd-DTPA) has been safely used in over 45 million MRI procedures since its introduction in 1988, with adverse events (AEs) reported in less than 0.01% of cases, indicating a strong safety profile.

The analysis revealed that while serious AEs accounted for only 9.3% of reports, there were significant regional differences in AE reporting, with the U.S. reporting nearly double the AEs compared to Europe, highlighting the importance of ongoing pharmacovigilance.

In a study involving 19 individuals with chronic incomplete spinal cord injury and 16 healthy controls, specific measures of spinal cord atrophy (anterior-posterior width and left-right width) were found to correlate with sensory and motor outcomes, indicating their potential as reliable indicators of functional impairment.

The research suggests that these MRI-derived measurements can independently assess sensory and motor functions, aligning with the anatomical locations of the main sensory and motor pathways in the spinal cord.

In a study involving 103 medical and neurologic inpatients, 89% of physicians found that MR imaging significantly enhanced diagnostic information, aiding in diagnosis, treatment planning, and prognosis estimation.

MR imaging was particularly beneficial in cases of diagnostic uncertainty, as it more often decreased confidence in incorrect presumptive diagnoses rather than increasing it.
