Abstract: Objective To evaluate the clinical value of 64-slice spiral CT,MRI + magnetic resonance cholangiopancreatography (MRCP) on suspected biliary obstruction.Methods Eighty-five patients with suspected biliary obstruction were examined by 64-slice spiral CT,MRI + MRCP,compared with the pathological results.The accuracy rate of CT,MRI + MRCP,CT + MRI + MRCP in evaluating the sites and nature of obstruction were calculated.Results The accuracy rate of evaluating the site of obstruction in CT was 96.5％ (82/85),MRI + MRCP was 97.6％ (83/85),difference was not statistically significant (P ＞ 0.05).The accuracy rate of evaluating the nature of obstruction in CT was 81.2％ (69/85),MRI + MRCP was 87.1％ (74/85),CT +MRI + MRCP was 94.1％ (80/85),there was no statistically significant difference between MRI + MRCP and CT with CT + MRI + MRCP (P ＞ 0.05),difference was statistically significant between CT and CT + MRI + MRCP (P ＜ 0.05).Conclusion A comprehensive analysis of CT,MRI + MRCP can increase the accuracy of diagnosis biliary obstruction.
