  To evaluate the preoperative biliary system of the Living liver transplantation donors using the MRCP after the fat meal.

     50 cases from May 2007 to December 2008 of the preoperative donors for Living liver transplantation were included 37 males and 13 females with an average age of （28.3±6.8） years old, with no surgical contraindication, and all have the corresponding operative cholangiography information. The MRCP of the donors for Living liver transplantation was scanned 6~19d before the operation. The MRCP was scanned before and 45 minutes after the fat meal (two fried eggs). 80ml-contrast-medium diluent (of 5ml-GD-DTPA liq for intravenous injection and 75ml-aq.dest.) was drunk 40 minutes after the fat meal. To analyze the demonstration quality of the secondary bile duct before and after the fat meal; to evaluate the increase of the demonstration rate through the changes of the image quality grades of the secondary bile duct. To conclude the anatomical types of the bile duct for the 50 cases in the MRCP after the fat meal; to calculate the coincidence rate of the secondary bile duct in the MRCP after the fat meal based on the corresponding operative cholangiography information.

  10% of the 50 cases in the MRCP before the fat meal can meet the diagnosis needs of the preoperative evaluation; 100% of the 50 cases in the MRCP after the fat meal can meet the diagnosis needs. The demonstration grades of the secondary bile duct in the MRCP after the fat meal were obviously superior to those before the fat meal. Five anatomical types of the bile duct have been discovered in this research. The coincidence rate of the secondary bile duct in the MRCP after the fat meal is 96%, based on the corresponding operative cholangiography information.

  The MRCP after the fat meal can clearly demonstrate the secondary bile duct and perfectly meet the needs of the preoperative evaluation of the Living liver transplantation.

The MRCP after the fat meal is a secure, effective, and easy-operating techonology for the preoperative evaluation of the biliary system of the living liver transplantation donors.
