The role of gadoxetic acid-enhanced magnetic resonance cholangiography in the evaluation of postoperative bile duct injury: pictorial essay

Abstract Iatrogenic lesion of the bile ducts is a relatively common occurrence during liver surgery, increasing morbidity and mortality rates. T2-weighted magnetic resonance cholangiography and gadoxetic acid-enhanced functional magnetic resonance cholangiography (fMRC) with administration of hepatobiliary-specific contrast medium (gadoxetic acid) are fundamental to the diagnostic imaging approach in patients with such lesions. Here, we present a review of the literature and suggest an imaging approach to biliary tract injury, focusing on clinical cases in which fMRC had an impact on the decision-making process for the management of the affected patients.

摘要：医源性胆管损伤在肝脏手术中相对常见，可增加患者的术后发病率与死亡率。T2加权磁共振胆管造影以及使用肝胆特异性对比剂（钆塞酸）的钆塞酸增强功能磁共振胆管造影（fMRC）是此类损伤患者诊断成像的核心方案。本文通过文献综述，针对胆道损伤提出影像学诊疗思路，重点探讨fMRC对患者临床管理决策流程产生影响的相关临床案例。
