What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new type of MRI, using perfluoropropane gas, to obtain clear lung images. The goal is to enhance imaging technology, enabling doctors to see lung details more clearly. Healthy volunteers who can hold their breath for 16 seconds and have a stable health history are ideal candidates for this study. As an unphased trial, it offers participants the chance to contribute to advancements in medical imaging technology.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the study team or your doctor.

What prior data suggests that this MRI technique is safe for healthy volunteers?

Research has shown that using 19F (a type of gas) in MRI scans is generally safe. One study found that inhaling this gas during an MRI caused no harmful effects. Although not officially approved for inhalation during medical procedures, past reports suggest its safety. Studies involving both healthy individuals and those with conditions like cystic fibrosis also showed no negative side effects from 19F MRI. These findings indicate that this method is safe, though further research could provide additional confirmation.12345

Why are researchers excited about this trial?

Researchers are excited about the use of 19F (perfluoropropane) MRI because it offers a new way to visualize lung function without relying on traditional imaging methods like X-rays or CT scans. Unlike standard imaging, which primarily shows the structure of the lungs, this MRI technique uses a special gas, perfluoropropane, to highlight how air moves and is distributed in the lungs, offering a more dynamic view. This could lead to better understanding and monitoring of lung health, particularly in conditions where traditional imaging falls short in capturing functional changes.

What evidence suggests that 19F MRI is effective for developing lung imaging techniques?

Research has shown that a special type of MRI using ¹⁹F (perfluoropropane) is a promising method for imaging the lungs. Studies have found that this technique consistently provides reliable images. In this trial, healthy volunteers will undergo ¹⁹F MRI to measure how well air moves in and out of the lungs. One study improved the process of capturing these MRI images, making them clearer and faster to obtain. Although researchers are still developing this technique, early results are promising in demonstrating its ability to capture detailed lung images.26789
