摘要
目的 探讨64层螺旋CT基于左前斜冠状位的最小密度投影(MinIP)联合曲面重组(CPR)在胆道疾病中的诊断价值.方法 将142例疑似胆道疾病患者随机分为试验组和对照组,每组71例.在常规C T增强的基础上,对照组行冠状面重组,试验组行以左前斜冠状位MinIP联合CPR对患者进行检测.比较两组胆道疾病的诊断结果.结果 试验组胆道疾病诊断的准确率、灵敏度、特异度、阳性预测值和阴性预测值分别为98.59% 、100.00% 、95.65% 、97.96% 、100.00%,对照组分别为90.14% 、89.36% 、91.67% 、95.45% 、81.48%;试验组准确率、灵敏度及阴性预测值高于对照组,差异有统计学意义(P<0.05).结论 64层螺旋CT基于左前斜冠状位MinIP联合CPR对胆道疾病的诊断具有较高价值,是一种简洁方便、准确可靠的检查技术,值得推广应用.
Objective To explore the diagnostic value of 64-slice spiral CT minimum-density projection (MinIP) based on left anterior oblique coronary combined with curved surface reconstruction for biliary tract diseases. Methods A total of142 patients suspected of biliary tract disease were randomly divided into the experimental group and the control group with 71 cases in each group,and the control group underwent conventional dynamic enhanced CT scan and coronary reconstruction,the experimental group adopted MinIP based on left anterior oblique coronary combined with curved surface reconstruction on the basis of conventional dynamic enhanced CT.The diagnostic results of two groups were compared. Results Compared with final diagnosis,the accuracy,sensitivity,specificity,positive predictive value and negative predictive value of the control group were 90.14%,89.36%,91.67%,95.45% and 81.48% respectively,which of the experimental group were 98.59 %,100.00%,95.65%,97.96% and100.00% respectively.The diagnostic accuracy,sensitivity and negative predictive value of the experimental group were significantly higher than those of the control group ( P<0.05 ). Conclusion 64-slice CT MinIP based on left anterior oblique coronary combined with curved surface reconstruction has shown high diagnostic value in the diagnosis of biliary tract diseases,and as a simple,convenient,accurate and reliable examination technique,it is worthy of spread and application.
