What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores a new type of MRI using hyperpolarized Xenon gas to better understand lung function in healthy individuals. The goal is to develop tools for evaluating lung ventilation and image quality. Individuals in stable health who can hold their breath for 16 seconds and have no history of lung or heart issues might be suitable candidates. Participants will undergo lung function tests and the special MRI scan during the trial. As an unphased trial, this study offers participants the opportunity to contribute to groundbreaking research that could enhance future lung imaging techniques.

Do I have to stop taking 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.

What prior data suggests that hyperpolarized Xenon MRI is safe for healthy volunteers?

Research has shown that hyperpolarized Xenon-129 MRI is safe and well-tolerated. In a study with 44 participants, all handled the xenon inhalations without serious side effects or significant changes in vital signs. Another review found no major adverse effects, reporting only mild side effects. Xenon-129, a stable, nonradioactive gas, is used in these scans, making it a safe option for imaging.12345

Why are researchers excited about this trial?

Researchers are excited about Hyperpolarized Xenon MRI because it offers a novel way to visualize lung function in real time, unlike traditional imaging methods like CT scans and standard MRIs, which primarily show structural details. This technique uses hyperpolarized xenon gas, allowing for a detailed view of how air moves through the lungs, potentially catching early signs of lung issues before they become apparent with current methods. By providing a clearer picture of lung health, it could lead to earlier and more accurate diagnoses, improving patient outcomes.

What evidence suggests that hyperpolarized Xenon MRI is effective for evaluating ventilation defects?

Studies have shown that hyperpolarized Xenon-129 MRI provides a detailed view of lung function. This imaging method identifies breathing problems and detects lung disease early, before symptoms worsen. Research indicates that this technique excels at identifying lung issues, such as chronic obstructive pulmonary disease (COPD) and asthma. The method is noninvasive, requiring no surgery or internal devices, and uses a safe contrast agent to enhance image clarity. Overall, evidence supports its potential to improve the diagnosis and monitoring of lung problems. Participants in this trial will undergo this imaging technique to further explore its capabilities in healthy volunteers.13678

Are You a Good Fit for This Trial?

This trial is for healthy adults aged 18 to 85 with a BMI between 18 and 40, who can perform breathing tests and hold their breath for at least 16 seconds. People with certain medical devices, metal in their body, heart or lung problems, pregnancy, or severe claustrophobia cannot participate.
