The purpose of this study is to observe transient dyspnea pattern after Gd-EOB-DTPA administration by obtaining continuous dynamic T1 weighted image data.
Study Type
OBSERVATIONAL
Enrollment
60
standard dose of gadoxetic acid (0.025mmol/kg) intravenous administration
Dynamic T1 weighted sequence consist of precontrast, arterial, portal, transitional and hepatobiliary phases. precontrast, arterial and portal phases (prior to contrast media injection to 60 seconds after contrast media injection) are obtained continuously in free-breathing state. Transitional and hepatobiliary phases are obtained in breath-hold state.

Number of Participants With Transient Dyspnea.
A sudden onset irregular breathing pattern after EOB administration, based on MRI k-space data (not participants' symptom). The k-space data was analyzed after the enrollment completion.
Time frame: during 3 minutes after contrast media administration
Duration of Transient Dyspnea in Participants With Transient Dyspnea.
The duration of transient dyspnea was analyzed based on the MRI k-space data, using a dedicated software. The analysis using the MRI k-space data was performed after the completion of enrollment.
Time frame: during 3 minutes after contrast media administration
