目的　探讨磁共振仿真胆道镜（ＭＲＶＣ） 诊断胆石症的价值。方法　３０ 例胆石症患者行了冠状面二维ＨＴ２ＦＳＥ序列薄层无间隔扫描，在工作站用导航技术作内镜成像等后处理。７ 例胆囊切除术后，４ 例胆囊严重萎缩且充满结石者未获胆囊内镜影像。结果　所有段以上胆管（１００ ％ ） 和２１ 例胆囊（２１／２５ ，８４ ％ ） 成功地获得了胆道镜样图像。胆石症患者检出率为９６７ ％ （２９／３０） ，长径２ ～２０ｍ ｍ 胆道结石均得以清晰显示。源影像见水线征（ｈｙｄｒｏｌｉｎｅｓｉｇｎｓ） 的结石内镜影像上呈边缘光滑且与管壁锐角相交的结节，水线征不完整或消失者呈与管壁钝角相交的结节；多发散在者呈路石样、聚集者呈小石堆样等改变。３ 例常规ＭＲＩ误诊的胆囊结石并胆囊癌有特征性表现而获确诊。发现１ 例（３３ ％ ，１／３０）假阳性结果。结论　磁共振仿真胆道镜成像为无创性内镜样显示胆道解剖的有效手段，对胆石症及结石状态和并发症有一定的诊断价值 Objective To investigate the value of magnetic resonance cholangiography (MRVC) in the diagnosis of cholelithiasis. Methods Thirty patients with cholelithiasis underwent coronary angiography with two-dimensional non-septal scanning of two-dimensional HT2-FSE sequence and post-processing at the workstation using navigation technique such as endoscopic imaging. Seven cases of cholecystectomy, 4 cases of severe gallbladder atrophy and full of stones were not endoscopic gallbladder imaging. Results All the choledochles (100%) and 21 cases of gallbladder (21/25, 84%) were successfully obtained choledochoscope-like images. The detection rate of patients with cholelithiasis was 96.7% (29/30), and the length of 2 ~ 20m m biliary stones were clearly shown. Source images of hydro-linesigns (hydro-linesigns) on the endoscopic images were smooth edges and intersections with acute angles of the nodules, water line signs are not complete or disappeared obtuse angle with the tube wall nodules; multiple divergence In the road was stone-like, gathered were small stone-like change. 3 cases of conventional MRI misdiagnosed gallbladder stones and gallbladder carcinoma have been characterized by the performance of diagnosis. One case (33%, 1/30) of false positive results was found. Conclusion Magnetic resonance cholangiopancreatography is an effective means of noninvasive endoscopic imaging of biliary tract anatomy and has certain diagnostic value on the status and complications of cholelithiasis and stones
