目的评价磁共振胆胰管成像(MRCP)结合轴位薄层T2WI-SPAIR对胆系结石的诊断价值。方法对104例经手术及病理证实为胆系结石患者图像进行分析,全部使用2D-MRCP、3D-MRCP及轴位薄层T2WI-SPAIR,比较分析增加轴位薄层T2WI-SPAIR扫描前后对胆系结石的诊断符合率。结果 MRCP与增加轴位薄层T2WI-SPAIR后诊断符合率分别为62.50%、96.15%,比较差异有统计学意义(P<0.01)。结论 MRCP结合轴位薄层T2WI-SPAIR对胆系结石,尤其是小结石及泥沙样结石具有极高的诊断价值。
Objective To evaluate the value of magnetic resonance cholangiopancreatography (MRCP) combined with axial thin layer T2WI-SPAIR in the diagnosis of gallstone. Methods The images of 104 cases with gallstone confirmed by operation and pathology were analyzed. 2D-MRCP, 3D-MRCP and axial T2WI-SPAIR were all used to compare the changes of axial and axial T2WI-SPAIR Department of stone diagnosis in line with the rate. Results The coincidence rates of MRCP and axial T2WI-SPAIR were 62.50% and 96.15%, respectively, with significant difference (P <0.01). Conclusion MRCP with axial thin layer T2WI-SPAIR of gallstones, especially small stones and sediment-like stones with high diagnostic value.
