Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Liver MRI

In this study, MRI refers to phase-contrast 4D flow sequence.

Group Type EXPERIMENTAL

Liver MRI

Intervention Type DIAGNOSTIC_TEST

Liver MRI including 4D flow sequence is performed twice in liver transplantation recipients, before and 1 month-after transplantation.

In donor candidates, liver MRI including 4D flow sequence is performed twice in 1-3 weeks to assess repeatability of the technique.
