磁共振胆管造影诊断胆石症65例

MAGNETIC RESONANCE CHOLANGIOGRAPHY FOR DIAGNOSIS OF CHOLELITHIASIS IN 65 CASES

目的: 探讨磁共振( MR) 胆管造影对胆石症的诊断价值和限度。方法: 用重T2 加权快速自旋回波序列作MR 胰胆管造影263 例, 采集资源影像后作最大信号强度投影3 D 重建。结果: 发现65 例胆结石。胆总管结石( 或伴胆囊、肝内胆管结石) 54 例, 其中嵌顿性结石19 例、非嵌顿性结石30 例、复合性胆总管结石5 例; 胆囊结石( 或伴胆管扩张) 11 例。其MR 胆管造影表现, 各具有形态特征。结论: MR 胆管造影能确定胆石的存在、大小和数目,诊断准确性高、定位精确。它属非侵袭性影像检查技术, 安全、有效, 特别适用于不准备作介入治疗的胆石症者,

Objective:To explore the diagnosis value and limitation of magnetic resonance cholangiography(MRC) for cholelithiasis.Methods:MR cholangiopancreatography by using heavily T 2 weighted fast spin echo sequence was performed in 263 cases to acquire image and postprocedure processing with a maxmium intensity projection 3 D reconstruction.Results: MRC image of diagnostic quality were obtained in all cases.Of them,65 cases of bile stone were revealed:19 impacted calculus,30 nonimpacted calculus,five complex common duct calculus,and 11 gallbladder stone.The image findings of the biliary tree excellcucy in MRC have characteristic,which are suggestive of the presence and number of calculi.Conclusion:With MRC allowed noninvasive, bile duct calculi can be diagnosed with a high accuracy,which is similar to that with endoscopic retrograde cholangiopancreatography and percutaneous transhepatic cholangiography.It may be used in patients with no obvious reason for interventional treatment.
