Primary Outcome Measures

Name	Time	Method
primary endpoint: MRI scanner-related conditions Imaging Timing Setting Technique Voxel Size Matrix K-space Ordering Data Acquisition Time (time to take arterial phase images) Reduction Factor for Parallel Imaging Flip Angle Fat Suppression Technique Magnetic Field Strength EOB administration-related conditions Rate of Administration of EOB Amount of Saline for Flushing; The correlation between the occurrence of truncation artifacts in arterial phase images after administration of EOB and these EOB-enhanced dynamic MRI imaging conditions will be statistically analyzed.

Secondary Outcome Measures
