摘要
目的：评价磁共振胰胆管成像（ＭＲＣＰ）的临床应用价值。材料与方法：在ＰｈｉｌｉｐｓＧｙｒｏｓｃａｎＴ１０ＮＴ１．０Ｔ超导型磁共振成像仪上进行ＭＲＣＰ检查５８例，其中作为正常对照组１６例，各种胰胆管病变者４２例。ＭＲＣＰ采用不屏气涡轮自旋回波（ＴＳＥ）序列的重度Ｔ２加权像扫描（ＴＲ／ＴＥ＝２０００ｍｓ／７００ｍｓ），并应用呼吸触发及脂肪抑制技术。图像后处理以最大强度投影法（ＭＩＰ）进行三维（３Ｄ）重建。结果：５８例ＭＲＣＰ检查均一次成功，５７例胰胆管显示满意，其效果类似于直接胰胆管造影图像。１６例正常对照者，胆囊、肝外胆管及部分肝内胆管和主胰管的解剖形态显示清晰。４２例胰胆管病变者，ＭＲＣＰ可显示各种病变的影像学特征，总的诊断符合率为８５．７％（３６／４２），对胆道梗阻程度的判断和定位诊断准确性为１００％（３７／３７），定性诊断准确性为８３．８％（３１／３７）。ＭＲＣＰ诊断胆总管结石和恶性胆道梗阻的准确性分别为９０．９％（１０／１１）和８０．０％（１２／１５）。结论：研究表明，ＭＲＣＰ检查成功率高，胰胆管显示清晰，对各种胰胆管病变的临床应用适应症广泛，诊断价值可靠，尤其是在直接胰胆管造影失败或检查不完全时，?
Objective: To evaluate the clinical application of MR cholangiopancreatography (MRCP).Materials and Methods:On a Philips Gyroscan T10 NT 1.0T superconductive MR imaging unit, MRCP was performed in fifty eight cases, including sixteen persons as comparison and forty two patients with various pancreaticobiliary duct diseases. MRCP used non breath hold heavily T 2 weighted turbo spin echo (TSE) sequence with respiratory triggering and fat suppression techniques (TR/TE=2000/700ms). Postprocedure processing with a maximum intensity projection (MIP) algorithm was made for three dimensional (3D) reconstruction.Results:MRCP examination was succeeded in all fifty eight cases and the pancreaticobiliary duct was shown satisfactorily in fifty seven cases. The images of MRCP were similar to those of direct cholangiopancreatography. In sixteen persons as comparison, gallbladder, extrahepatic bile duct and partial intrahepatic bile duct or main pancreatic duct were visualized clearly. In forty two patients with pancreaticobiliary duct disease, MRCP can exhibit the imaging characteristics of various pancreaticobiliary duct diseases and the total diagnostic accuracy was 85.7% (36/42). The accuracy of MRCP in the detection of the degree and location of bile duct obstruction was 100% (37/37). The accuracy of MRCP for evaluating the causes of obstruction was 83.8% (31/37). For the diagnosis of choledocholithiasis and malignant bile duct obstruction, the accuracy of MRCP was 90.9% (10/11) and 80.0% (12/15), respectively.Conclusion: This study shows that MRCP examination has a high success rate and can depict pancreaticobiliary duct clearly. Because of extensive indication and reliable value in diagnosing pancreaticobiliary duct diseases, MRCP may provide an efficient alternative to direct cholangiopancreatography, especially when the diagnostic ERCP and PTC are unsuccessful or inadequate.
