Study 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
Primary Outcome
Image quality of liver MRI scans will be assessed by quantifying the degree of respiratory motion artifacts under two breath-holding conditions: Functional Residual Capacity (FRC) alone and FRC with oxygen supplementation. Reduced artifacts indicate improved image clarity and feasibility of the technique. Unit of Measure: Motion artifact score (ordinal scale, e.g., 1-5).
