摘要
目的探讨多排螺旋CT(MDCT)扫描在成人继发性肺结核(PTB)治疗及随访中的应用。方法回顾性分析108例成人继发性PTB的临床资料,比较治疗前、治疗后、随访6个月时MDCT的征象变化。结果治疗后,各活动性CT征象的检出率均较治疗前明显降低(P <0. 05),随访6个月,肺叶/肺段实变、树芽征、厚壁空洞的检出率较治疗前明显降低(P <0. 05),而磨玻璃密度影、气道壁增厚则无明显差异(P>0. 05);各转归CT征象的检出率在治疗结束后均明显增加,随访6个月,纤维灶、机化实变的检出率较治疗前有所降低,但差异均无统计学意义(P> 0. 05),钙化灶、支气管束聚拢迂曲、支气管扩张的检出率与治疗前比较均无明显差异(P> 0. 05)。结论成人继发性PTB具有典型的CT征象,细菌学治愈后病变转归仍处于演变阶段,MDCT扫描对成人继发性PTB的抗结核疗效评价及治愈后的定期随访具有重要的临床价值。
Objective To explore the application of multi-detector computed tomography （MDCT） scanning in treatment and follow-up in adult patients with secondary pulmonary tuberculosis （PTB）. Methods The clinical data of 108 adult patients with secondary PTB were retrospectively analyzed, and the change of MDCT signs were compared before and after treatment and 6 months of follow-up. Results After treatment, the detection rate of activity CT signs were significantly reduced compared with before treatment （ P〈 0.05）. 6 months after followed-up, pulmonary lobe/pulmonary segments consolidation and thick-walled cavity reduced more significantly than after treatment （ P〈 0.05）, while ground-glass opacity and thicken of airway wall showed no significant difference （ P〉 0.05）. The detection rate of conversion CT signs all increased significantly after treatment （ P〈 0.05）. 6 months after following-up, the detection rate of fibrosis and consolidation decreased after treatment, but there was no significant difference （ P〉 0.05）, and the detection rate of calcifications, bronchus clustered and bronchiectasis had no obvious difference （ P〉 0.05）. Conclusion There are typical CT signs in adult patients with secondary PTB, which is still in the stage of evolution of lesion outcome after bacteriologically cured. MDCT scanning is helpful in the efficacy evaluation of anti-tuberculosis and regular follow-up after curing.
