This study investigated the feasibility of optimized breath-hold compressed-sensing accelerated magnetic resonance cholangiography (BH-CS-MRCP) in visualizing the biliary system in living donor liver transplantation (LDLT) donors. Conventional navigator-triggered (NT) MRCP was performed preoperatively, and optimized BH-CS-MRCP was performed both preoperatively and one month after surgery. The optimized BH-CS-MRCP protocol showed similar motion or blurring artifacts, overall image quality, background suppression, and biliary duct depiction compared with conventional NT-MRCP protocols. This suggests that optimized BH-CS-MRCP with a short acquisition time (17 s) can be used for preoperative and postoperative evaluation of biliary ducts in LDLT donors.
