Optimizing Liver MRI Using Breath-Holding With and Without Oxygen
NCT07135401 · Status: RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 10
Last updated 2026-04-13
Summary
The goal of this interventional study (clinical trial) is to learn if different breath-holding techniques, with and without extra oxygen, can improve the quality of abdominal Magnetic Resonance Imaging (MRI) images in healthy adults, ages 18-75.
The main questions it aims to answer are:
* Does breath-holding at end-expiration improve image quality in abdominal MRI scans?
* Does adding oxygen while breath-holding further reduce motion artifacts in abdominal MRI scans?
Researchers will compare breath-holding with and without oxygen to see if using oxygen improves image quality during MRI scans.
Participants will:
* Be pre-screened for MRI safety and trained on breath-hold procedures
* Have one non-contrast abdominal MRI scan at the University of California San Francisco (UCSF) China Basin Imaging Center
* Use two different breath-holding techniques during the scan, with and without oxygen
* Complete one study visit lasting about 45 minutes to 1 hour
