About this trial

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
