MRI for Non-Invasive Imaging in Neonates and Children

United States45 participantsStarted 2011-01-01

Plain-language summary

The purpose of this study is to develop rapid MRI techniques for imaging the lung with hyperpolarized helium-3 gas as an inhaled contrast agent. These techniques will be piloted in adults and older children before testing them in younger children and infants. The purpose is to enable imaging of non-sedated infants by imaging so fast as to freeze motion.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * MRI sequence development (n=40): Healthy subjects and patients with CF, BPD, or asthma will be used in the development of the rapid imaging techniques. These subjects will be age 4 months to 65 years old. Healthy subjects can have no history of chronic respiratory disease. The subjects with CF or asthma must have a physician diagnosis of their respective disease. * Proof-of-Concept Study (n=30): Ten healthy infants,10 infants with CF, and 10 infants with BPD age 4-24 months will be imaged in the proof-of-concept study. Healthy infant must have had an uncomplicated term birth and have no history of chronic respiratory symptoms. The patients with CF must have a physician diagnosis of CF and be at their baseline clinical status on the day of imaging. Exclusion Criteria: * Any condition for which a MRI procedure is contraindicated. * Presence of any non-MRI compatible metallic material in the body, such as pacemakers, metallic clips, etc. * Likelihood of claustrophobia * Chest circumference greater than that of the helium magnetic resonance (MR) coil. * Pregnancy, by report of subject. Clinically in the Department of Radiology at UVA, self report is used when screening patients for MR scans as well as CT scans and fluoroscopy studies. If the subject reports there is any chance of their being pregnant a urine pregnancy test will be performed prior to any imaging.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
