The purpose of this study is to evaluate a single breath hold abdominal MRI protocol and compare the image quality of respiratory triggered 3D T1-weighted images against conventional breath hold images.

The study will acquire extra image sets using DISCO LAVA with one breath hold during the arterial imaging phase. No additional breath holds will be required. 1. Respiratory-triggered T1w DISCO LAVA precontrast 2. Respiratory-triggered T1w DISCO LAVA in the portal venous phase 3. Respiratory-triggered T1w DISCO LAVA in the equilibrium phase

Motion Artifact Scores
Three investigators will independently evaluate MRI examinations. They will assign motion scores between respiratory triggered and corresponding breath hold acquisitions. 1 = no motion artifact; 2 = minimal motion artifact, no effect on diagnostic quality; 3 = moderate motion artifact with some, but not severe, effect on diagnostic quality; 4 = severe motion artifact, images degraded but interpretable; and 5 = extensive motion artifact, images nondiagnostic.
Time frame: During MRI, up to 60 minutes
Noise Scores
Three investigators will independently evaluate MRI examinations. They will assign noise scores between respiratory triggered and corresponding breath hold acquisitions. 1 = no noise artifact; 2 = minimal noise artifact, no effect on diagnostic quality; 3 = moderate noise artifact with some, but not severe, effect on diagnostic quality; 4 = severe noise artifact, images degraded but interpretable; and 5 = severe noise artifact, images nondiagnostic.
Time frame: During MRI, up to 60 minutes
