Objective To investigate the X-ray findings of pulmonary tuberculosis in order to improve the correct diagnosis rate. Methods A retrospective analysis was made on the CT and X-ray findings of 65 cases of pulmonary tuberculosis with complete clinical data and the combination of sputum test. Results Image performance: (1) patchy, patchy shadows; (2) hollow shadow; (3) nodules, spherical shadows; (4) mixed performance. Sputum collection bacteria smear acid-fast bacilli in 40 cases; 25 cases of negative, experimental anti-TB treatment significantly improved or basically absorbed. Conclusions Various manifestations of pulmonary tuberculosis are complicated by X-ray combined with sputum smear or CT examination to improve early diagnosis. Anti-TB treatment should be given after 2 weeks of anti-inflammatory treatment
