摘要
目的:探究64排螺旋CT诊断肺结核的价值。方法:选取2021年10月—2022年12月广州市胸科医院收治的100例疑似肺结核患者为研究对象,全部患者均进行64排螺旋CT检查,以病原学检查结果为金标准,评估64排螺旋CT对肺结核的诊断效能,经Kappa检验分析64排螺旋CT检查与金标准的一致性,统计64排螺旋CT对肺结核影像征象的检出情况。结果:经病原学检查结果确诊95例肺结核。64排螺旋CT检查结果显示,阳性91例,阴性9例。64排螺旋CT诊断肺结核的诊断灵敏度、准确率、特异度、阴性预测值、阳性预测值分别为94.74%(90/95)、94.00%(94/100)、80.00%(4/5)、44.44%(4/9)、98.90%(90/91)。以痰液培养结果显示结核分枝杆菌阳性为金标准,64排螺旋CT诊断与金标准的一致性较好,Kappa值=0.818。64排螺旋CT检出结节28例(30.77%)、空洞40例(43.96%)、实质性病变34例(37.36%)、钙化灶58例(63.74%)、支气管狭窄50例(54.95%)、磨玻璃影征象47例(51.65%)。结论:应用64排螺旋CT诊断肺结核的效能较高,与金标准的一致性较好,且能够清晰反映肺内病灶情况。
Objective To explore the diagnostic value of 64-row spiral CT in the diagnosis of pulmonary tuberculosis.Methods From October 2021 to December 2022,100 patients with suspected pulmonary tuberculosis admitted to Guangzhou Chest Hospital were selected as the research subjects,and all patients underwent 64-row spiral CT examination.The diagnostic efficacy of 64-row spiral CT for tuberculosis was assessed.The consistency of 64-row spiral CT examination with gold standard was evaluated by Kappa test.The detection of pulmonary tuberculosis imaging signs by 64-row spiral CT was counted.Results Etiological examination results confirmed 95 cases of pulmonary tuberculosis.The results of 64-row spiral CT examination showed that 91 cases were positive and 9 cases were negative.The sensitivity,accuracy,specificity,negative predictive value and positive predictive value of 64-row spiral CT in the diagnosis of pulmonary tuberculosis were 94.74%(90/95),94.00%(94/100),80.00%(4/5),44.44%(4/9)and 98.90%(90/91),respectively.The sputum culture results showed that Mycobacterium tuberculosis was positive as the gold standard,and the diagnosis of 64-row spiral CT was consistent with the gold standard(Kappa=0.818).Among of them,28 cases(30.77%)of nodules,40 cases(43.96%),34 cases(37.36%)of parenchymal lesions,58 cases(63.74%)of calcified foci,50 cases(54.95%)of bronchial stenosis,and 47 cases(51.65%)of ground-glass imaging were detected by 64-row spiral CT.Conclusion The use of 64-row spiral CT to diagnose pulmonary tuberculosis has high efficiency,good consistency with the gold standard,and can clearly reflect the lesions in the lungs.
