Application of CT Image in Diagnosis of Pulmonary Tuberculosis

Abstract

In order to study the diagnosis of computed tomography (CT) image-assisted pulmonary tuberculosis patients, patients who are diagnosed as tuberculosis in Wuhan No. 6 Hospital Affiliated to Jianghan University are selected as a research object, and multi-slice spiral CT and routine X-ray examination are performed. By analyzing and comparing multi-slice spiral CT and routine X-ray examination, the diagnostic value of tuberculosis is evaluated and the detection rate of lesions in the lung and clinical classification of tuberculosis are also evaluated (including the anterior segment of the upper lobe, the posterior segment of the superior lobe, the dorsal segment of the lower lobe, the basal segment of the lower lobe, and concealment). The results show that compared with conventional X-ray examination, the sensitivity and accuracy of multi-slice spiral CT examination for diagnosis of pulmonary tuberculosis are higher, and the difference is statistically significant. In the upper part of the upper lobe, the posterior part of the upper lobe, the lower part of the lower lobe, and the tuberculosis lesions in the basal segment and hidden part of the lower lobe, the detection rate of multi-slice spiral CT examination is significantly higher than the X-ray examination, and the difference is statistically significant. In the diagnosis of tuberculosis classification, the misdiagnosis rate of multi-slice spiral CT examination is significantly lower than the conventional X-ray examination, and the difference is statistically significant. Therefore, CT images have important reference value in the diagnosis of tuberculosis, the examination of lesions, and the clinical classification of tuberculosis. Although there are still some shortcomings in the research process, it still provides some basis and ideas for more precise research.
