摘　　要：目的探讨胆总管癌的MSCT动态增强特点及其应用价值。方法收集经病理学证实且MSCT资料完整的胆总管癌62例,并对MSCT各期中肝外胆管癌的显示率、表现进行回顾性分析。结果 CT增强扫描,56例肿瘤动脉期或门脉期明显强化;11例肿瘤延迟期呈延迟性强化。动脉期,37例肿瘤即可被检出,59例肿瘤门脉期清晰显示,61例肿瘤延迟期清晰显示。结论 MSCT增强检查可以准确显示肿瘤特点,是诊断胆总管癌的有效方法之一。Objective To analyze the CT findings of the cholangiocarcinoma in common bile duct and to evaluate its diag-nostic value .Methods Sixty-two patients of cholangiocarcinoma with surgically and pathologically proved underwent mul-tiphasic 16-slce spiral computed tomography （MSCT ） scans ,which comprised precontrast plain scans and contrast-en-hanced arterial phase ,portal venous phase ,and delayed phase scans .The detection rate and findings of cholangiocarcino-ma in all patients on various phase CT images were analyzed retrospectively .Results Among 62 cases ,the middle or over enhancement of cholangiocarcinoma was found in 56 during arterial or portal venous ,and the delayed enhancement of cholangiocarcinoma of 32 was found in 11 in the delayed phase .The EHCC lesions during arterial ,portal venous ,and de-layed phase were found in 37 ,59 and 61 cases ,respectively .Conclusion MSCT enhancement scanning could accurately show the location and extent of EHCCs so that it has important significance for the pre-operative diagnosis .
