摘要
目的探讨磁共振胆胰管成像（ＭＲＣＰ）对低位胆系梗阻性疾病的临床诊断价值。方法对４４例结石、壶腹肿瘤、胰头癌、胆管癌及炎症患者进行ＭＲＣＰ成像，并对照内窥镜逆行胰胆管造影（ＥＲＣＰ）及手术病理结果分析。结果（１）因梗阻部位和程度不同，ＭＲＣＰ对胆胰管各部的显示率为５７．０％～１００．０％；（２）扩张胆管表现为枯枝样、软藤样、腊肠样；（３）梗阻端呈倒杯口状、截断状、乳头状、串珠状、鼠尾状；（４）本组ＭＲＣＰ定位诊断率为１００．０％，定性诊断率为８６．４％。结论ＭＲＣＰ对低位胆系梗阻性疾病定位诊断准确，结合源像对结石的定性诊断特异性较高，对其他病变定性尚待深入探讨。
? Purpose To evaluated the clinical diagnosis value of lowlevel biliary obstructive disease by magnetic resonance cholangiopancreatography(MRCP) imaging. Methods 44 patients with choledocholithiasis, ampullar tumor, pancreatic head carcinoma, cholangiocarcinoma and inflammation were examined by MRCP. The results of MRCP, ERCP pathology were analysed. Results The demonstrating rates of each parts of cholangiopancreatic duct were 57.0%—100.0%, depending on obstructive level and degree. Dilated biliary ducts appeared “withered tree brancheslike”,“soft caneslike”, and “sausagelike”. Obstructive ends exhibited “down cup mouthform”,“cut offform”, “nippleform”, “string beadsform”, and “mouse tailform”. Diagnostic rate of MRCP for obstructive level was 100.0%, the specificity for the cause of obstruction was about 86.4%. Conclusion MRCP can accurately define the obstructive site in lowlevel biliary obstructive disease. The specificity for the diagnosis of choledocholithiasis is very high when combining with resource images for analysis, but it specificity for the diagnosis of other diseases needs further research.【
