Methods: We retrospectively analyzed the MPMRI findings of 317 patients out of 1080 cases with LT, admitted to the Fundeni Clinical Institute from January 2005 to June 2025, who developed biliary complications. Results: Biliary complications after LT evaluated by MPMRI included anastomotic strictures in 235 cases (74%), intra-or extrahepatic bile leaks/biloma in 56 patients (18%), secondary cholangitis due to pyogenic cholangitis in 91 cases (29%), liver abscesses in 23 patients (7%), BT lithiasis in 27 patients (8.5%), disease recurrence in 26 cases (8%), and extrinsic BT compression in 1 case (0.3%) . Conclusions: MPMRI plays a crucial role for the evaluation of BT complications, with the protocol being optimized in correlation with the clinical question or suspicion and with the clinical status of the patient.  \nKeywords: liver transplantation; biliary tree complications; MPMRI; hepatospecific contrast material  \n1. Introduction  \nComplications occurring after liver transplantation (LT) can be classified according to the time of onset, such as early (\u003C3 months) or late (>3 months), or according to their cause, including surgical (vascular, biliary, or parenchymal), graft-related, immunologic, infectious, and neoplastic, as illustrated in Figure 1 [1–5] . Biliary tree (BT) complications represent the most frequent post-LT complications, with an incidence of 5–25%, particularly in patients undergoing right-lobe living donor transplantation, and they typically occur during the first postoperative month [1,6,7] . The most common causes of BT complications after LT are hepatic artery thrombosis or stenosis, accounting for 90% and 70% of cases, respectively [6,8–10] . BT complications represent a major cause of morbidity and mortality among LT patients, with an incidence of 10–32%[1] . These complications primarily include anastomotic strictures, bilomas, secondary cholangitis, hepatic abscesses, lithiasis, recurrence of primary sclerosing cholangitis (PSC), and extrinsic compression of the biliary ducts, all of which significantly impact patient survival and the need for retransplantation [1,3,11] . The most frequent biliary complication is biliary obstruction caused by anastomotic or  \nnon-anastomotic strictures (biliary ischemia, pretransplantation biliary disease and infection, papillary dyskinesia due to devascularization/denervation of the ampulla of Vater, orbiliary stones) [8–10] .  \nFigure 1.
