摘要
目的 观察薄层CT多征象联合多平面重组(MPR)诊断气管支气管结核(TBTB)的价值。方法 回顾性分析234例接受胸部薄层CT扫描的TBTB患者并行MPR,观察病变直接与间接表现;比较轴位平扫CT(直接观察法)与其联合MPR(联合观察法)的诊断效能。结果 直接观察法诊断TBTB的敏感度、特异度、阳性预测值、阴性预测值及准确率分别为38.88%(201/517)、98.13%(1 789/1 823)、85.53%(201/235)、84.99%(1 789/2 105)及85.04%(1 990/2 340),联合观察法上述各项分别为91.10%(471/517)、98.85%(1 802/1 823)、95.54%(471/493)、97.51%(1 802/1 848)及97.14%(2 273/2 340);2种方法间敏感度、阳性预测值、阴性预测值及准确率差异均有统计学意义(P均<0.001),而特异度差异无统计学意义(P>0.05)。结论 根据薄层CT多征象联合MPR可有效诊断TBTB。
Objective To observe value of thin slice CT multiple signs combined with multiplanar reformation(MPR)for diagnosing tracheobronchial tuberculosis(TBTB).Methods Data of 234 TBTB patients who underwent chest thin slice CT scanning were retrospectively analyzed.MPR was performed,the direct signs and indirect signs of TBTB were observed.The diagnostic efficacy of axial plain CT images(direct observation)and of MPR combined with the former(combined observation)were compared.Results The sensitivity,specificity,positive predictive value,negative predictive value and accuracy of direct observation was 38.88%(201/517),98.13%(1789/1823),85.53%(201/235),84.99%(1789/2105)and 85.04%(1990/2340),respectively,of combined observation was 91.10%(471/517),98.85%(1802/1823),95.54%(471/493),97.51%(1802/1848)and 97.14%(2273/2340),respectively.Significant differences of sensitivity,positive predictive value,negative predictive value and accuracy were found(all P<0.001),whereas no significant difference of specificity was found between 2 methods(P>0.05).Conclusion Thin slice CT multiple signs combined with MPR could be used to effectively diagnose TBTB.
