Role of multislice CT and magnetic resonance cholangiography in preoperative evaluation of potential donor in living related liver transplantation

The aim of this study was to evaluate the role of multislice CT (MSCT) an magnetic resonance cholangiography (MRC) in evaluation of potential donors in living related live transplantation Patients and methods: Twenty-five potential donors included in our study. All potential donor underwent 1st step medical examination and laboratory investigations to enter the 2nd step investigations with MSCT for calculation of the hepatic parenchymal CT density, reconstruction o hepatic vascular anatomy and CT volumetry. Magnetic Resonance cholangiography (MRC) an intra-operative cholangiography (IOC) were done on only 23 patients for biliary tree assessment Results: Of the 25 patients evaluated by MSCT, 23 patients (92%) were accepted. Two patient (8%) were excluded from surgery because of anatomical criteria, regarding portal vein variant based on CT findings. One showed right anterior portal vein arising from left portal vein and th other showed trifurcation of the main portal vein Conclusion: Multislice CT is a valuable tool in the evaluation of potential living liver donors that provides complete information on the hepatic vascular anatomy, the liver parenchyma, an volumetric measurements. MRC with a 3.0-T MR system demonstrates the preoperative biliar evaluation very well with a high accuracy rate
