磁共振胆胰管成像对肝胆胰疾病的诊断价值

Value of Magnetic Resonance Cholangiography in Diagnosing Diseases of the Biliary System

本文通过分析12例不同肝胆胰疾病患者的磁共振胰胆管成像（MRCP）并与手术结果相对照，探讨MRCP对肝胆胰疾病的诊断价值。在常规腹部MR扫描后，加扫重T2加权快速自旋回波序列，所得图像用计算机进行后处理，形成类似造影效果的重叠图像。在12例患者中，MRCP清楚显示扩张的肝内、肝外胆管及梗阻部位的有11例。作者还结合文献复习，总结了MRCP与ERCP各自的特点。

The purpose of this artical is to assess the diagnostic value of magnetic resonance cholangiopancreatography (MRCP). A heavily T2 - weigted fast spin echo sequence was used for magnetic resonance imaging of the biliary system in twelve patients with various pancreatiobiliary diseases and images were postprocessed by using a maximum - intensity projection algorithm. Results of MRCP were compared with those of the operation. MRCP can accurately demonstrated the anatomy of the dilated intrahepatic and extrahepatic bile ducts and level of obstruction in 11 patients. Differing from ERCP,MRCP is noninvasive and does not require administration of contrast medium.
