胆总管恶性梗阻的磁共振胰胆管成像研究

目的:探讨磁共振胰胆管成像(MRCP)对梗阻性黄疸定位、定性的诊断意义。方法:对27例经MRCP诊断为胆总管恶性梗阻患者的MRCP及MRI图像进行分析并与病理结果进行对照。结果:MRCP均满意地显示了梗阻及狭窄的部位和断端的形态。梗阻部位为肝门部8例,胆总管下部19例。恶性梗阻26例中胆管突然截断22例,向心性狭窄4例。结论:MRCP可在一定程度上反映胆道梗阻的性质,能够较好地评价胆道系统的正常与病理解剖,是诊断胆道病变一种非常有效的方法。

Application of MRCP and MRI in the diagnosis of malignant biliary obstruction

Objective To investigate the diagnostic value of magnetic resonance(MR) imaging and magnetic resonance cholango-pancreatography (MRCP) in positioning and qualitationing malignant biliary obstruction. Method The MRCP and MRI image results of 27 malignant biliary obstruction cases diagnosed by MRCP were analyzed and compared with pathology results. Results MRCP could clearly show the blocked and stenotic location. Of 27 cases, 8 cases were the hepatic hilum bile duct obstructions, others were located at inferior part of common bile duct. Of the 26 cases of malignant biliary obstruction,bile ducts were resented abruptly interruption in 22 cases and stenosis in 4 cases sign. Conclusions MRCP is the noninvasive technique for depicting the pancreatic-bile ducts. Combined with MR scan, it is helpful in evaluating the site and etiology of bile duct obstruction.
