目的：探讨活动性肺结核（PTB）CT表现与痰涂片抗酸杆菌（AFB）数量的关系。方法：回顾性分析173例活动性肺结核患者的CT资料。根据痰涂片上AFB的数量将患者分组如下：A，阴性（n = 40）; 13，可疑（n = 2 1）; C，+（n = 34）;和D，++或更大（n = 78）。记录是否存在小叶、结节、实变和空洞，以及小叶的数量、空洞的数量和空洞腔的最大直径。结果：四组间微小结节和结节的发生率无显著差异。相反，随着AFB数量的增加，固结和空化的频率增加（P <0.05）。
Purpose: To investigate the relationship between computed tomography (CT) findings in patients with active pulmonary tuberculosis (PTB) and the number of acid-fast bacilli (AFB) on sputum smears. Methods: We reviewed CT scans of 173 patients with active PTB. The patients were divided into groups according to the number of AFB on sputum smears as follows: A, negative (n = 40); 13, doubtful (n = 2 1); C, + (n = 34); and D, ++ or greater (n = 78). The presence or absence and the number of lobes that included micronodules, nodules, consolidation and cavitation, the number of cavities and the maximum diameter of the cavity lumen were noted. Results: The frequency of micronodules and nodules did not significantly differ among the four groups. In contrast, the frequency of consolidation and cavitation increased with the number of AFB (P
