Abstract
Objective To investigate the diagnostic value of 64-slice spiral CT scan and MRI scan in cholangiocarcinoma .Method Clinical data of 34 patients with cholangiocarcinoma were retrospectively analyzed.All the patients were examined with 64-slice spiral plain and dynamic enhanced scan ,and MRI plain and dynamic enhanced scan .Effect of the two detection means on the diagnosis of cholangiocarcinoma were analyzed .Results In 34 patients with cholangiocarcinoma , the discovery rate of tumor type was significantly higher than that of intraductal growth type , infiltrating stenosis type and unclear type .The image quality of 64-slice spiral CT scan (grade Ⅰ29 cases,grade Ⅱ5 cases,grade Ⅲ0 case)was significantly better than that of MRI scan (grade Ⅰ16 cases,grade Ⅱ14 cases,grade Ⅲ4 cases).The difference was statistically significant ( P<0 .05 ) .The discovery rate of irregular type was higher than that of round or round-like type .The discovery rate of nodular growth type was higher than that of cauliflower intrductal growth type .The discovery rate of patchy infiltrating stenosis type was higher than that of stellate infiltratingstenosis type .The positioning accuracy rate and the qualitative accuracy rate of 64-slice spiral CT scan were obviously higher than those of MRI scan , and the difference was statistically significant (P<0.05).Conclusion 64-slice spiral CT scan and MRI scan are both effective methods in the diagnosis of cholangiocarcinoma ,the image with 64-slice spiral CT scan is more clear and accurate .关键词
