All About Multiparametric MRI Evaluation in Biliary Tree Complications After Liver Transplant

Area of Science:

• Radiology
• Hepatobiliary Surgery
• Transplant Medicine

Background:

• Biliary tree (BT) complications are a significant concern following liver transplantation (LT).
• Effective evaluation of these complications is crucial for patient management and outcomes.
• A multidisciplinary approach is essential for personalized treatment strategies.

Purpose of the Study:

• To highlight the utility of multiparametric magnetic resonance imaging (MPMRI) in evaluating biliary complications post-LT.
• To illustrate the role of MPMRI within a multidisciplinary team framework for patient care.
• To discuss and present findings related to various biliary complications detected by MPMRI.

Main Methods:

• Retrospective analysis of 1080 liver transplant cases.
• Focus on 317 patients with diagnosed biliary complications.
• Evaluation of multiparametric magnetic resonance imaging (MPMRI) findings.

Main Results:

• MPMRI identified various biliary complications including anastomotic strictures (74%), bile leaks/biloma (18%), and secondary cholangitis (29%).
• Other identified complications included liver abscesses (7%), BT lithiasis (8.5%), disease recurrence (8%), and extrinsic BT compression (0.3%).
• The study analyzed a substantial cohort, providing robust data on complication prevalence.

Conclusions:

• Multiparametric magnetic resonance imaging (MPMRI) is a critical tool for diagnosing biliary tree complications after liver transplantation.
• Optimizing MPMRI protocols based on clinical context enhances diagnostic accuracy.
• MPMRI integration supports personalized treatment planning in post-liver transplant care.
