Dynamic Enhanced CT Diagnosis of Hilar Cholangiocarcinoma / 实用放射学杂志

Objective To assess the value of spiral CT in the diagnosis of hilar cholangiocarcinoma.Methods 13 patients of hilar cholangiocarcinoma underwent CT plain and dynamic enhanced scan.CT findings were analysed in comparison with that of surgery and pathology.Results On plain scan,the lesions appeared as soft tissue mass with low density in hepatic hilar(n=11),bile duct wall irregularly thickened and bile duct narrowed(n=2).On dynamic enhanced scan,delayed enhancement was seen in 13 cases.Conclusion Plain spiral CT and dynamic enhanced scan have great value in showing the morphological features and improving the diagnosis of hilar cholangiocarcinoma.
