Endoscopic Retrograde Cholangiopancreatography (ERCP) remains the conventional method of imaging the pancreatic and biliary tree and is performed by direct injection of iodinated contrast material via the major papilla. This diagnostic procedure gained popularity in the 1970s and subsequently paved way for ERCP guided interventions such as sphincterotomy, stone retrieval and stent placement. Currently, therapeutic ERCP is more widespread than diagnostic ERCP primarily due to the availability of noninvasive imaging. Nevertheless, more than half a million ERCPs are performed annually in the United States and radiologists need to be comfortable interpreting them. The following review will familiarize the reader with the imaging appearances of biliary and pancreatic disorders on conventional ERCP, and elaborate on therapeutic ERCP with illustrative examples.
经内镜逆行胰胆管造影术（ERCP）仍然是对胰腺和胆道成像的常规方法，通过主要乳头直接注射碘造影剂进行。这项诊断程序在 20 世纪 70 年代流行起来，随后为 ERCP 引导的介入治疗铺平了道路，如括约肌切开术、取石和支架放置。目前，由于非侵入性成像的可用性，治疗性 ERCP 比诊断性 ERCP 更为广泛。尽管如此，每年仍有超过 50 万例 ERCP 在全美范围内进行，放射科医生需要能够熟练解读这些 ERCP 结果。以下综述将使读者熟悉常规 ERCP 对胆道和胰腺疾病的影像学表现，并通过实例详细阐述治疗性 ERCP。
