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.
Efficacy
Not applicable
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.
(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
Observational

Male and Female
(1) Patients who undergo an EOB-enhanced dynamic MRI scan performed in accordance with the product information approved in Japan during the past one year before the time when it becomes possible to start this study at each institution on and after April 1, 2013 (will be enrolled in this study consecutively in an unselected manner)
(2) Patients who undergo an EOB-enhanced dynamic MRI scan at a magnetic field strength of 1.5 T or higher using a fat-suppressed 3D-gradient echo (GRE) sequence with an MRI scanner manufactured by GE, SIEMENS, PHILIPS, or TOSHIBA
(3) Inpatient or outpatient
(4) Male or female patients
(5) Patients aged 20 or more and less than 85 years
(6) Patients with a serum creatinine level below the institutional upper limit of normal
(7) Patients with liver disease of any etiology
(8) Patients with a body weight below 100 kg
(9) Patients who are awake and alert
(10) Patients prescribed with EOB in accordance with the product information approved in Japan
(1) Patients with documented occurrence of motion artifacts (due to inappropriate breath holding) in MR images taken before use of EOB
(2) Patients with portal vein thromboembolism30)
(3) Patients with multiple (10 lesions or more) or giant hepatic mass lesions (60 mm or more)30)
(4) Patients in whom MRI is contraindicated (with a pacemaker implanted)
(5) Patients with known hypersensitivity to gadolinium contrast media
(6) Patients with bronchial asthma or serious allergies
(7) Patients with serious renal impairment
(8) Pregnant or nursing patients
(9) Patients listed in the enrollment log redundantly
(10) Any others judged ineligible for enrollment in this study by the investigator at each institution

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.
