目的:分析对肺结核患者采用多层螺旋CT的价值.方法:择取时间范围:2020年5月至2021年5月,在我院进行检查的疑似肺结核患者(n=800),回顾性分析所有患者采用X线、多层螺旋CT进行检查,将痰培养、痰涂片作为金标准,评估两种诊断方式诊断符合率、敏感度、特异度.结果:(1)比较X线诊断情况:在金标准结果下,经X线诊断符合率67.38％(539/800),敏感度为67.69％(528/780),特异度为55.00％(11/20).(2)比较多层螺旋CT诊断情况:在金标准结果下,经多层螺旋CT诊断符合率9“,”Objective: To analyze the value of multi-slice spiral CT for pulmonary tuberculosis patients. Methods: Selection time range: From May2020 to May 2021, patients with suspected tuberculosis (n=800) undergoing examinations in our hospital were retrospectively analyzed and all patients were examined by X-ray and multi-slice spiral CT, and the sputum was examined. Culture and sputum smear are used as the gold standard to evaluate the diagnostic coincidence rate, sensitivity, and specificity of the two diagnostic methods. Results: (1) Comparison of X-ray diagnosis: Under the gold standard results, the coincidence rate of X-ray diagnosis was 67.38％ (539/800), the sensitivity was 67.69％ (528/780), and the specificity was 55.00％ (11/ 20). (2) Comparing the diagnosis of multi-slice spiral CT: Under the gold standard result, the diagnostic coincidence rate of multi-slice spiral CT is 90.38％ (728/800), the sensitivity is90.77％ (708/780), and the specificity is 75.00％ ( 15/20). (3) Compare the diagnostic accuracy of the two diagnostic methods: the coincidence rate, sensitivity, and specificity of multi-slice spiral CT are higher than those of X-ray, and the contrast is statistically different (P ＜ 0.05). Conclusion: The diagnosis of pulmonary tuberculosis patients with multi-slice spiral CT can not only make the initial diagnosis of pulmonary tuberculosis, but also observe the internal conditions of tuberculosis lesions, and the diagnostic accuracy rate is high.
