目的 探讨磁共振胆胰管成像(MRCP)在胆道恶性梗阻病例的诊断价值。材料方法 搜集20例胆道恶性梗阻病例的MRCP图像进行分析,包括胆管癌11例,胰头癌4例,原发性肝癌3例,其它2例。结果 除显示梗阻端以上的胆管扩张外,胆管癌的阻塞端可显示截断或鼠尾状改变;肝门区胆管癌及胆总管胰以上段癌尚可显示梗阻远侧未扩张胆管;胰头癌可见扩张胆总管下段突然中断,胆总管下段移位,胰管扩张;原发性肝癌主要显示肝门区胆管受累情况。结论 MRCP在胆道恶性梗阻病例的诊断中有重要价值。
Objective To investigate the diagnostic value of magnetic resonance cholangiopancreatography (MRCP) in patients with malignant biliary obstruction. Materials Methods MRCP images of 20 cases of malignant biliary obstruction were collected and analyzed including 11 cases of cholangiocarcinoma, 4 cases of pancreatic head cancer, 3 cases of primary liver cancer and 2 cases of the other cases. Results In addition to showing obstruction above the bile duct dilatation, cholangiocarcinoma obstruction can show truncated or rat caudate-like changes; hilar cholangiocarcinoma and common bile duct pancreatic cancer can still show obstruction of the distal non-dilated bile duct; pancreatic cancer Shows that the expansion of the common bile duct suddenly interrupted the lower section of the common bile duct shift, pancreatic duct dilatation; primary liver cancer hilar duct bile duct involvement. Conclusion MRCP in the diagnosis of biliary malignant obstruction has an important value.
