| 目的：探讨活动性肺结核痰涂片中抗酸杆菌(AFB,acid-fast bacilli)的含量与HRCT征象的关系。
方法：回顾性分析200例活动性肺结核患者的痰涂片结果和HRCT图像，根据痰涂片镜检结果分为5组，涂阴组、涂阳1+组、涂阳2+组、涂阳3+组、涂阳4+组，每组40例。在不知痰涂片镜检结果的前提下，由3名主治医师对各例胸部HRCT图像进行阅片，统一意见后逐一记录每例胸部HRCT表现及特点。对比分析各组间HRCT征象的差异。
结果：小叶中心结节、腺泡结节、树芽征、磨玻璃影、肺实变、支气管损害及空洞是活动性肺结核常见的HRCT表现，总检出率分别为55%、48%、48%、44%、57%、56%、48%；腺泡结节、树芽征、肺实变、支气管损害和空洞等HRCT表现检出率随痰涂片中AFB含量增多而增加，涂阳4+组中空洞检出率与其它组有显著差异；小叶中心结节和磨玻璃影在各组间无差异；HRCT显示病灶分布随痰涂片中AFB含量增高而增多。
结论：活动性肺结核痰涂片AFB的含量与HRCT征象有关，HRCT征象在一定程度上可反映痰涂片中AFB的含量。 |

| Objective:To evaluate the relationship between HRCT sings and the content of sputum smear acid-fast-bacilli(AFB) in active pulmonary tuberculosis.
Methods:A retrospective analysis of 200 patients with active tuberculosis sputum smear results and HRCT images.According to the result of sputum smear microscopy was divided into 5 groups,smear-negative group,the smear-positive case 1+,2+,3+,4+group,40 cases in each group.On the premise of don’t know the sputum smear microscopy results,three attending physician read all cases of chest HRCT images,to reach a consensus,then they record each HRCT manifestations and characteristics.Comparative analysis of HRCT manifestations of differences between groups.
Results:HRCT manifestations in active pulmonary tuberculosis:The total positive rate of centrilobular nodules,alveolar nodules,tree-in-bud,ground-glass opacity,real variable,bronchial damage,cavity were 55%,48%,48%,44%,57%,56%,48%;respectively,alveolar nodules,tree-in-bud,real variable,bronchial damage,cavity,the detection rate increases with the content of AFB in the sputum smear.The smear-positive cavity detection rate in smear-positive 4+ group and other groups have significant differences,P<0.05. Centeilobular nodules and ground-glass opacity have no difference between the groups;HRCT shows that lesions distribution increased with the content of AFB in the sputum smear.
Conclusion:The content of active tuberculosis sputum smear AFB associated with HRCT Findings,HRCT Findings to a certain extent,can reflect content of AFB in sputum smear. |
