Objectives
Narrative objectives1 The objective of the present study is to retrospectively investigate the correlation between EOB-enhanced dynamic MR imaging conditions and the occurrence of truncation artifacts in EOB-enhanced dynamic MR arterial phase images for each manufacture of the major MRI scanners used in Japan in order to determine what conditions are most correlated with the occurrence of truncation artifacts.

Assessment
Primary outcomes 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.
Key secondary outcomes (1) Distribution of the scores of truncation artifacts by EOB-enhanced dynamic MRI imaging condition
(2) Correlation between the conspicuity of lesions and the distribution of the scores of truncation artifacts

Since this study is a retrospective, non-interventional, observational study, explanations about this study to each patient by the investigator/sub-investigator will be omitted, or informed consent from each patient will be replaced by disclosure of study-related information in compliance with the "Ethical Guidelines for Clinical Studies" published by the Ministry of Health, Labour and Welfare and the provisions at each institution.

Since this study is a retrospective, non-interventional, observational study, collection of safety information, such as the occurrence of adverse events, including a follow-up assessment of such events will not be performed.
