摘　　要：目的:探析在肺结核治疗后复查病例诊断中进行低剂量螺旋CT检查与X线胸片技术检查的准确性。方法:选取2017年5月-2020年6月我院收治的60例肺结核患者作为观察对象,根据不同的检查方法分为CT组和X线组,CT组30例患者均采用低剂量螺旋CT进行检查,X线组30例患者均采用X线胸片技术检查。分析两种方法的诊断结果。结果:CT组诊断准确率93.33%明显高于X线组70.00%;CT组和X线组支气管播散灶检出率分别为63.33%、46.67%,卫星灶检出率分别为56.67%、40.00%,空洞检出率分别为86.67%、60.00%,淋巴结肿大检出率分别为13.33%、3.33%,胸膜增厚检出率分别为20.00%、46.67%,胸水检出率分别为13.33%、3.33%,两组对比差异较大(P<0.05);同时,CT组和X线组对肺结核诊断的敏感度分别为83.59%、71.52%,特异度分别为86.49%、74.92%,阳性预测值分别为86.29%、70.42%,阴性预测值分别为83.92%、70.42%,两组对比差异较大(P<0.05);与X线组的检查满意度(86.67)相比,CT组腹检查的满意率(96.67)更高,两组对比差异较大(P<0.05)。结论:在肺结核治疗后复查病例中采用低剂量螺旋CT的诊断准确率明显高于X线胸片,且CT的肺结核病理特征检出率较高,有助于减少误诊,改善医患关系,可在临床上进一步推广。Objective:To explore the accuracy of low-dose spiral CT and X-ray in the diagnosis of pulmonary tuberculosis after treatment.Methods:A total of 60 patients with pulmonary tuberculosis were selected as the observation objects,all from May 2017 to June 2020,and they were divided into CT group and X-ray group according to different examination methods.30 patients in CT group were examined by low-dose spiral CT,and 30 patients in X-ray group were examined by X-ray chest film technology.The diagnosis results of the two methods were analyzed.Results:The diagnostic accuracy of CT group was 93.33%,which was significantly higher than that of X-ray group(70.00%).The detection rates of bronchial dissemination,satellite focus,cavity,lymphadenopathy,pleural thickening and pleural effusion were 63.33%and 46.67%,56.67%and 40.00%,86.67%and 60.00%,13.33%and 3.33%respectively There was significant difference between the two groups(P<0.05).At the same time,the sensitivity,specificity,positive predictive value and negative predictive value of CT group and X-ray group were 83.59%,71.52%,86.49%,74.92%,86.29%,70.42%,respectively.There was a big difference between the two groups(P<0.01)Compared with X-ray group(86.67),the satisfaction rate of abdominal examination in CT group(96.67)is higher,and there is a big difference between the two groups(P<0.05).Conclusion:The diagnostic accuracy of low-dose spiral CT is significantly higher than that of X-ray chest film,and the detection rate of pathological features of pulmonary tuberculosis by CT is higher,which helps to reduce misdiagnosis andimprove the doctor-patient relationship,can be further promoted in clinic.
