目的：对比分析新发型、复发型及慢性肺结核CT征象。方法2011年9月~2013年9月在我院就诊的49例新发型肺结核、51例复发型肺结核及50例慢性肺结核患者进行螺旋CT检查，对比分析3种类型肺结核的CT征象。结果活动性肺结核CT征象包括树芽征、肺实变、毛玻璃阴影、节段性分布小叶中心结节影在新发型及复发型肺结核中的检出率显著高于慢性肺结核（P<0.01），但在新发型及复发型肺结核患者之间无显著差异（P>0.05）。厚壁空洞在慢性肺结核中的检出率显著高于新发型及复发型肺结核（P<0.01），但在新发型及复发型肺结核患者之间无显著差异（P>0.05）。非活动性肺结核CT征象包括支气管聚拢迂曲、肺气肿、纤维条索影、钙化在慢性肺结核中显著高于新发型及复发型肺结核（P<0.05）；且在新发型及复发型肺结核中也存在显著差异（P<0.05）。结论活动性及非活动性肺结核的CT征象在新发、复发及慢性肺结核中存在显著差异，有助于诊断肺结核活动性。

Objective To comparatively analyze the CT (Computerized Tomography) ifndings 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 ifndings 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 ifndings of active pulmonary TB including the tree-in-bud pattern, pulmonary consolidation, ground-glass opacity and segmental or lobar consolidation;no signiifcant 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.
