[CT and MRT following liver transplantation]

Area of Science:

• Radiology
• Transplant Surgery
• Medical Imaging

Background:

• Liver transplantation is a complex procedure with numerous potential technical complications.
• Post-transplant complications require accurate and timely diagnosis for effective management.
• Various imaging modalities are employed to assess the outcomes of liver transplants.

Purpose of the Study:

• To evaluate the utility of Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) in diagnosing post-liver transplant complications.
• To determine the complementary role of CT and MRI in specific clinical scenarios.

Main Methods:

• Review of imaging findings in patients who underwent liver transplantation.
• Analysis of CT for hepatic parenchyma and perihepatic fluid collections.
• Assessment of CT's role in clarifying unclear sonographic findings for vascular or biliary issues.
• Evaluation of MRI's contribution, particularly in complex venous hemodynamics.

Main Results:

• CT is highly effective for assessing the liver's parenchyma and detecting perihepatic fluid collections.
• CT provides crucial complementary information when ultrasound findings are equivocal for vascular or biliary complications.
• The definitive role of MRI in liver transplant evaluation is still under investigation.
• MRI can provide significant additional information in cases with complex venous hemodynamics.

Conclusions:

• CT is a valuable tool for evaluating liver transplant recipients, particularly for parenchymal changes and fluid collections.
• CT serves as an important adjunct to ultrasound for diagnosing vascular and biliary complications.
• Further research is needed to fully establish the role of MRI in liver transplant assessment, although it shows promise for complex vascular issues.
