PDFAbstract
Objective To compare the diagnostic value of MSCT and MRCP+MR in biliary obstructive lesions. Methods 66 patients with bile duct obstruction treated in our hospital from January 2013 to August 2015 were selected as the research objects. All patients underwent MSCT and MRCP combined with MR examination. Imaging findings of the two methods were observed. The results of surgical pathology were taken as the standard to statistically analyze and compare the coincidence rates of positioning and qualitative diagnosis of the two examination methods. Results In terms of positioning diagnosis, the total coincidence rate of CT was 97.0%(64/66) while of MRI was 100.0% (66/66)(P＞0.05); In terms of qualitative diagnosis, the coincidence rates of CT in the diagnosis of benign lesions was 76.2%(32/42) while of MRI was 88.1% (37/42)(P＞ 0.05). The coincidence rates of CT in the diagnosis of malignant lesions [75.8%(18/24)] was lower than that of MRI [95.8%(23/24)](P＜0.05). Conclusion Both of MSCT and MRCP+MR have good effects in the diagnosis of biliary obstructive lesions while MRCP+MR has higher diagnostic accuracy in the diagnosis of malignant lesions and higher clinical value.
