This work was done to compare the validity of various imaging methods, e.g. ultrasonography (US), computed tomography (CT), endoscopic retrograde cholangiopancreatography (ERCP), percutaneous transhepatic cholangiography (PTC), and, especially, magnetic resonance cholangiopancreatography (MRCP) for extrahepatic bile duct carcinoma.
Sixty-five such patients who were operated and confirmed by pathology were used. Sixty patients had been examined by US; 52 by CT; 20 by ERCP; 9 by PTC and 20 by MRCP. The results of these imaging methods were compared with those of operative and pathological findings.
The diagnostic accuracy rates of site location were US 81.7%, CT 84.6%, ERCP 75.0%, PTC 88.9% and MRCP 100%, respectively. The quality diagnostic accuracy rates were US 73.3%, CT 82.7%, ERCP 75.0%, PTC 88.9% and MRCP 95.0%, respectively.
MRCP is superior to US, CT, ERCP and PTC not only in demonstrating the position but also the nature of extrahepatic bile duct carcinoma.
开展本研究以比较各种成像方法，如超声检查（US）、计算机断层扫描（CT）、内镜逆行胰胆管造影（ERCP）、经皮肝穿刺胆管造影（PTC），尤其是磁共振胰胆管造影（MRCP）对肝外胆管癌的诊断准确性。
选取65例经手术及病理确诊的此类患者。60例患者接受了超声检查；52例接受了CT检查；20例接受了ERCP检查；9例接受了PTC检查；20例接受了MRCP检查。将这些成像方法的结果与手术及病理检查结果进行比较。
病变部位诊断准确率分别为：超声检查81.7%、CT检查84.6%、ERCP检查75.0%、PTC检查88.9%、MRCP检查100%。定性诊断准确率分别为：超声检查73.3%、CT检查82.7%、ERCP检查75.0%、PTC检查88.9%、MRCP检查95.0%。
MRCP在显示肝外胆管癌的位置及性质方面优于超声检查、CT检查、ERCP检查和PTC检查。
