摘　　要：目的探讨MRI常规扫描结合弥散加权成像、MRCP在肝门胆管癌中的诊断价值。方法分析20例经手术病理或穿刺活检证实为肝门胆管癌患者的MRI图像资料,20例患者术前均行MRI常规平扫及动态增强扫描加弥散加权成像、MRCP检查,判断肿瘤发生的部位及浸及范围,以及周围血管、淋巴、脏器情况。结果 20例患者作MRI常规平扫及动态增强扫描加弥散加权成像、MRCP检查,16例经手术病理证实,4例经穿刺活检证实,MRI诊断和病理或穿刺活检结果一致的20例。结论 MRI增强前后可以显示肝门胆管癌的特征性改变,如结合MRI弥散加权成像、MRCP的扫描图像,更有利于提高肝门胆管癌的定位、定性诊断准确率,对术前评估的也是一种有效的方法。Objective To explore the value of routine MRI plain and dynamic enhanced scan with diffusion weighted im- agingand MRCP in the diagnosis of hilar cholangiocarcinoma. Methods Analysis of 20 cases confirmed by operation and patholo- gy or biopsy confirmed for the patients with hilar cholangiocarcinoma MRI image data. 20 patients underwent routine MRI plain and dynamic enhanced scan with diffusion weighted imaging, MRCP examination. To determine the position of tumor and extension of tumor, as well as peripheral vascular, lymphatic, organ case. And compared with pathology results analysis. Results 20 patients refelTed for routine MRI plain and dynamic enhanced scan with diffnsion weighted imaging and MRCP, In 16 cases confirmed by operation and pathology, 4 cases confirmed by biopsy. MRI diagnosis and pathology or biopsy results of 20 cases. Conclusion MRI before and after the increase of hilar cholangiocarcinoma can show characteristic changes, such as conthination of MRI diffu- sion weighted imaging, MRCP scanning image, more conducive to the enhancement of hilar cholangiocarcinoma localization, quali- tative diagnosis accuracy rate, the preoperative assessment is a kind of effective method.
