现代影像学技术的发展应用，有助于充分了解先天性胆管扩张症（congenital biliary dilatation，CBD）的类型及合并症，对制订完善的手术治疗方案有重要意义。超声、CT检查，因其无创伤性，为CBD最常用的诊断方法。其他检查方法包括磁共振胰胆管造影（MRCP）、经皮经肝胆道造影（PTC）、内镜下逆行胰胆管造影（ERCP）、术中胆道造影等，可显示整个胆道情况。

Abstract    The development of modern imaging technology could help the diagnosis of congenital biliary dilatation (CBD) type and complications, which is very important on making complete treatment. Ultrasonography and CT examination are the most commonly used diagnostic methods for CBD because of their non-invasiveness. Other methods are mainly through the ways of biliary tract imaging showing the entire biliary tract conditions, including magnetic resonance cholangiopancreatography (MRCP), percutaneous transhepatic angiography (PTC), endoscopic retrograde cholangiopancreatography (ERCP), intraoperative cholangiography and so on.
