目的：分析胆道梗阻病变应用多排螺旋CT多平面重建与曲面重建诊断的效果。方法方便选择该院于2014年11月—2016年1月收治的60例胆道梗阻病变患者，以抽签方式分为两组。对照组30例，应用超声诊断；观察组30例，应用多排螺旋CT多平面重建与曲面重建诊断。比较两组诊断符合率及准确率。结果观察组诊断指标符合率比对照组高，差异有统计学意义(P<0.05)；观察组诊断假阳性率为3.33%，假阴性率3.33%，真阳性率93.33%，真阴性率0.00%，对照组诊断假阳性率13.33%、假阴性率16.67%，真阳性率70.00%，真阴性率0.00%，观察组准确率比对照组高，差异有统计学意义(P<0.05)。结论多排螺旋CT能够清楚显示胆道结构与梗阻情况，诊断符合率和准确性较高，值得应用推广。“,”Objective To analyze the biliary obstruction based on multiple row spiral CT multiplanar reconstruction and curved surface reconstruction in the diagnosis of the effect. Methods Convenient select 60 patients from November 2014 to January 2016 with biliary obstruction, with lottery is divided into two groups. Control group 30 cases, the application of ul-trasonic diagnosis;Observation group of 30 cases, application more row spiral CT multiplanar reconstruction and curved sur-face reconstruction of diagnosis. Compare two groups of diagnostic coincidence rate and accuracy. Results Observation group index diagnosis coincidence rate is higher than the control group, significant difference (P<0.05);Observer group di-agnosis of false positive rate was 3.33%, false negative rate was 3.33%, the true positive rate 93.33%, true negative rate was 0.00%, the control group in the diagnosis of false positive rate and false negative rate 13.33% 16.67%, true positive rate 70.00%, true negative rate is 0.00%, observation accuracy is higher than control group, significant difference (P< 0.05). Conclusion Multiple row spiral CT can clearly show the structure and the obstruction of biliary tract, diagnostic coincidence rate and the accuracy is higher, is worth popularizing application.
