摘　　要：目的探讨超高场强MR用于胆管炎诊断的MRI特征。方法对8例胆管炎的MRI表现进行回顾性分析。结果胆囊切除术后并发感染性胆管炎2例,复发性化脓性胆管炎(recurrent pyogenic cholangitis,RPC)4例,自身免疫性胰腺炎(autoimmune pancreatitis,AIP)并发胆管炎2例。主要MRI所见:胆管形态的改变表现为狭窄与扩张;胆管壁的改变表现为增厚及强化;与胆管炎伴随的其它异常包括肝门血管鞘及邻近结构、胆管炎邻近的肝实质早期强化,肝实质小脓肿,胰腺形态及信号异常。结论 3.0T MR在胆管炎诊断中可获取更多的病理信息,其中,所反映出的病变区动脉过度灌注具有高敏感性,在胆管炎诊断中是有价值的MRI表现。肝胆胰的多序列高质量成像在相关疾病的鉴别中具有明显优势。Objective To evaluate ultra high-field Magnetic Resonance imaging in diagnosis and imaging features of cholangitis. Methods The authors completed a retrospective analysis of MRI findings in 8patients with cholangitis. Re- sults 2 patients had complicated with cholangitis postcholecystectomy 4 patients with recurrent pyogenic cholangitis （RPC）; 2 patients with autoimmune panereatitis （ALP）. MRI showed mainly： morphological changes of bile duct, with stricture and dilatation changes of bile duct wall, with thickness and contrast enhancement. Other abnormal signs with cholangitis were found including the early enhancements in the portal vaginae vasorum, adjacent structures and hepatic pa- renehyma near cholangitis area, mutiple small abscesses of hepatic parenchyma and pancreas＇s morphological and signal abnormity. Conclusion 3.0 T MR imaging in cholangitis can provide more pathologic details, and s MR enterrography with a 3.0 T scanner can provide more pathologic details, contrast agent enhancement effectness with high nensitivity could reflect arterial overperfusion in lesions, which could be the valuable imaging in diagnosis of cholangitis. The high- quality imaging of hepatic, biliary, pancreatic various series has significant advantages in identification of related diseases.
