The Multislice CT is considered a new advance in the field of diagnostic radiology and an important tool for investigating and imaging the liver.In our study , we used four channels MDCT to assess 31 donors before living related liver transplantation. The cases were supplied from the liver transplantation unit in El-Manial hospital ,where liver transplantation operations have been done for seven cases only. Preoperative imaging and assessment of the liver by the use of MDCT is one of the very important investigations required by both the donor and recipient and considered a great step in the field of liver imaging.
