Introduction: Preoperative mapping of the hepatic venous system is indispensable to the success of living related liver transplantation. The function of a new liver in the recipient and its regeneration depend on the inflow and outflow of the graft, respectively, and therefore the supplying and draining vessels are to be left intact. MR imaging of the liver has evolved in recent years mainly due to the development of fast imaging techniques that provide superior-quality, high-resolution images in a breath hold. A comprehensive MR imaging examination has the potential to serve as the sole preoperative imaging modality for a living adult-to-adult liver donor. Objective: To evaluate whether the hepatic veins can be visualized with a rapid noninvasive technique, and if so, whether the obtained images could be helpful in the planning for venous outflow reconstruction in living donor liver transplant. Materials and methods: 40 donors of LDLT had MR Venography as a mandatory step in our routine preoperative scanning procedure. The following findings were recorded: (1) tributaries of the middle hepatic veins (MHV) including segments V, VIII veins; (2) the presence of accessory inferior right hepatic vein (IRHV), or superficial right hepatic vein (SRHV); (3) the variable entering patterns of the RHV, MHV, and IRHV into IVC and (4) the diameter of the veins at their point of connection to the major veins. A comparison of the findings from the preoperative MR venography and the operative findings was made. Results: 30 cases out of 40 were with the same number of actual intra-operative hepatic veins in comparison with the pre-operative MRI Venography findings, and 10 cases with different intra-operative findings. Out of these 10, there were 4 cases only with Vessels diameter of more than 5mm (which were actually anastmosed) and 6 cases with Vessels diameter of less than 5mm (were not anastmosed) due to very tiny vessel diameter. The real discrepancy between preoperative estimates derived with MRI Venography and the intra-operative findings were only 4 cases (10%). Besides, we can also see that all of the six cases who needed the use of variable types of venous grafts for reconstruction were accurately determined on pre-operative MRI Venography. So that, the accuracy of pre-operative MRI Venography was at least 90%. Conclusion: In summary, we conclude that MRI is a fast and safe non-invasive method to study parenchyma and vasculature of the pre-transplant human donor liver with minimal interference with the transplant procedure. The hepatic veins with their confluence can easily be visualized thus allowing planning donor liver resection procedures.
