Ischaemic-type biliary lesion ITBL represents a serious complication after liver transplantation with potentially disastrous outcome, sometimes requiring re-transplantation. Distinguishing ITBL from other types of post-transplant biliary strictures is crucial. Magnetic-Resonance-Cholangio-Pancreatography (MRCP) is well established as a non-invasive imaging modality for the post-transplant investigation of the biliary system. The value of the individual imaging sequence in the diagnosis of ITBL is less clear. In this study we could demonstrate, that high resolution 3D-TSE yields best results in detecting and correctly diagnosing ITBL in liver transplant patients. SSFSE is also highly effective in classifying the type of the stricture.
