肝内胆管结石的影像学表现

Imaging features of intrahepatic stones

肝内胆管结石病变复杂、复发率高,常引起严重的并发症甚至癌变,多采用以手术为主的综合治疗.但术后残石率高,并发症多,术前影像学诊断不清和定位不准是原因之一.目前有多种常用影像检查可用以诊断肝内胆管结石,如直接胆道造影、B超、CT、MRCP等.因此,需掌握肝内胆管结石的影像学特征,合理选择并联合应用最有效的检查方法,方可为临床治疗提供重要的指导作用.

Intrahepatic stones is a complicated disease with a high recurrence rate and often leads to serious complications or even cancer. Surgery- based comprehensive treatment is always ad- opted, but inaccurate diagnosis and location in preoperative imaging are partly responsible for the high rate of residual stones and numerous complications postoperatively. There are several imaging modalities available for the diagnosis of intrahepatic stones, including PTC, ERCP, B-mode ultrasound, CT, and MRCP. Therefore, a better understanding of the imaging features of intrahepatic stones and selection of a reasonable combination of effective imaging methods can help improve outcome.
