简要总结
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.

研究组 & 干预措施
Breath hold Liver Acquisition with Volume Acquisition (LAVA)
Subjects will undergo abdominal MRI with LAVA with conventional breath holds (typically four or more breath holds) per standard of care.
Respiratory-triggered T1w DISCO LAVA
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.
干预措施: Respiratory-triggered T1w DISCO LAVA (Device)
结局指标
主要结局
Noise Scores
时间窗: During MRI, up to 60 minutes
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.
Motion Artifact Scores
时间窗: During MRI, up to 60 minutes
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.
