摘要
目的探讨磁共振胰胆管成像(MRCP)结合常规磁共振(MR)对恶性胆道梗阻的诊断价值。方法回顾性分析33例经手术、病理证实恶性胆道梗阻病例的MRCP、常规MR图像。结果梗阻部位分别为肝门部以上胆管,胰头上方胆总管水平,胰内段胆总管水平。所有病例均显示胆管扩张。梗阻末端胆管形态分别为乳头状、尖锥状、鸟嘴状、环状。常规MR图像可直接显示病变部位异常软组织信号,部分可见转移征象。MRCP定位准确率88%,定性准确率64%,MRCP结合常规MR定位准确率97%,定性准确率82%。结论MRCP结合常规MR检查明显提高恶性胆道梗阻诊断的准确率。
Objective To determine the value of conventional MR images as a supplement to MRCP images in the diagnosis of malignant biliary obstraction. Methods MRCP and MR features of 33 patients with malignant biliary obstruction diagnosed operatively and pathologically were retrospectively analyzed. Results Biliary obstruction originated from the bile duct above the hilar or the head of the pancreas, and inside the head of the pancreas. All cases showed bile dilation. The shape of stricture looked like as papilla or sharp awl , bird mouth, annulus. Conventional MR images showed abnormal signcal and metastasis. The accuracy of diagnosing the location of malignant biliary obstruction with MRCP was 88% ,which was 97% diagnosed by MRCP combined with MR imaging. The qualitative accuracy of diagnosis of malignant biliary obstruction with MRCP was 64 %, which was 82 % with both MRCP and MR. Condusion Use of conventional MR images with MRCP images significantly improved the diagnostic accuracy of malignant biliary obstruction.
