Objective To evaluate the clinical efficacy of 3D DCE MRA(three dimensional dynamic contrast-enhanced MR angiography)in patients of preoperation of liver transplantion.Methods 8 cases of potential liver transplant recipients suffering from severe liver disease underwent MRI and 3D DCE MRA, accessed the images synthetically. All of them had DUS examination, 4 cases received liver transplantation successfully.Results Satisfactory angiography images were obtained in all cases, the grade Ⅱ～Ⅲ branches of the hepatic artery, the grade Ⅱ～Ⅴ branches of the portal vein and gradeⅡ branches of the hepatic vein could clearly be visualized. Gastric-oesophageal varices were found in 3 cases of cirrhosis, compression and displacment of hepatic artery and portal vein were shown in one case of polycystic liver.Conclusion 3D DCE MRA is an efficiency, noninvasive technique, it offers great help in evaluating pre-operative vasculature of liver transplantation.
