Abstract：Objective To comparatively analyze the CT (Computerized Tomography) findings in newly-diagnosed, recrudescent and chronic pulmonary TB (Tuberculosis). Methods Spiral CT scanning was performed in pulmonary TB patients treated in the two hospitals from September, 2011 to September, 2013 (49 newly-diagnosed pulmonary TB cases; 51 recrudescent pulmonary TB cases; 50 chronic pulmonary TB cases). Comparative analysis of the CT findings in three types of cases was made. Results In comparison with the newly-diagnosed and recrudescent pulmonary TB, the chronic pulmonary TB (P<0.01) showed an obviously lower detection rate in CT findings of active pulmonary TB including the tree-in-bud pattern, pulmonary consolidation, ground-glass opacity and segmental or lobar consolidation; no significant difference existed between the newly-diagnosed and recrudescent pulmonary TB (P>0.05). The detection rate of the thick-walled cavity in the chronic pulmonary TB cases (P<0.01) was higher than that in newly-diagnosed and recrudescent pulmonary TB cases (non-existence of difference between the newly-diagnosed and recrudescent pulmonary TB, P>0.05). In comparison with the newly-diagnosed and recrudescent pulmonary TB, the chronic pulmonary TB (P<0.05) showed an obviously higher detection rate in CT findings of inactive pulmonary TB including bronchial flection, pulmonary emphysema, fibrotic bands and calcification; the significant difference existed between the newly-diagnosed and recrudescent pulmonary TB (P<0.05). Conclusion There were significant differences in the newly-diagnosed, recrudescent and chronic pulmonary TB, which helped to diagnose the activity of pulmonary TB.
