摘要
目的探讨螺旋CT及多平面重建在低位胆管梗阻中的诊断价值。方法收集74例低位胆管梗阻患者螺旋CT扫描及多平面重建资料,由两名医生采用单盲法分别对图像做出梗阻定位及定性诊断,并与其手术病理、经内镜逆行性胰胆管造影术或经皮肝穿刺胆道造影术结果对照。阅片者之间的差异性评价用Kappa一致性检验。结果两名医生的定位诊断准确率分别为89.2%、91.9%,定性诊断准确率分别为86.5%、85.1%,定位及定性诊断的K值分别为0.685、0.723。结论低张饮水后行螺旋CT扫描及其多平面重建有助于低位胆管梗阻的定位及定性诊断。
Objective To investigate the clinical value of multislice spiral CT（MSCT） and multi-planar reconstruction（MPR） in the diagnosis of low level biliary obstruction.Methods Data of spiral CT and MPR from seventy-four patients with low level biliary obstruction were collected and diagnosed blindly by two doctors about positioning and qualitative diagnosis.The results were compared with those obtained from pathological,ERCP or PTC examinations.The difference of diagnosis reported by two doctors was analyzed using Kappa test.Results The accuracy rates of two doctors were 89.2%（66/74）and 91.9%（68/74） for positioning and 86.5%（64/74）and 85.1%（63/74） for qualitative diagnosis,respectively（P〉0.05）.K values for positioning and qualitative diagnosis were 0.685 and 0.723,respectively.Conclusion MSCT scan and MPR are helpful to determine the positioning and qualitative diagnosis of low level biliary obstruction.
