目的 探讨不同分型支气管结 核患者多排螺旋MSCT影像学特征性。 方法 收集我院150例支气管结核患者影 像学资料，分析不同支气管结核患者的 MSCT影响学特征。结果 MSCT检测单侧 病变、双侧病变、支气管病变数、病变 气管等检出率与临床诊断无显著差异 (P>0.05)；MSCT诊断I-VI型支气管结核 患者的灵敏度依次为83.3％、94.7％、 90.9％、95.7％、92.8％、100.0％，特 异度依次为98.6％、97.3％、95.7％、 95.2％、97.1％、98.6％，准确率依次 为97.3％、96.7％、94.7％、95.3％、 96.7％、98.7％；I型MSCT表现为支气管 管壁增厚、管腔狭窄，II型表现为累及 各层气管，可不伴闭塞征但出现肺炎、 肺不张；III型表现为管壁增厚并出现增 生；IV型表现为支气管管腔明显狭窄， 可伴有闭塞征；V型表现为累及气管环， 管腔狭窄，可不伴闭塞征；VI型表现为 累及主支气管管腔，伴有结节并出现不 同程度狭窄。结论 不同分型的支气管患 者，其MSCT表现不一，临床可考虑使用 MSCT检查其疾病严重程度、病变范围及 疾病分期。

Objective To explore the multi-slice MSCT imaging features of patients with different types of bronchial tuberculosis. Methods The imaging data of 150 cases of patients with bronchial tuberculosis in our hospital were collected, and the MSCT imaging features of patients with different types of bronchial tuberculosis were analyzed. Results There was no significant difference in the detection rate of unilateral lesions, bilateral lesions, bronchial lesions and tracheal lesions by MSCT detection and by clinical diagnosis (P>0.05). The sensitivity of MSCT in diagnosing type I-VI bronchial tuberculosis patients was 83.3%, 94.7%, 90.9%, 95.7%, 92.8% and 100.0%, and the specificity was 98.6%, 97.3%, 95.7%, 95.2%, 97.1% and 98.6%, the accuracy rates were 97.3%, 96.7%, 94.7%, 95.3%, 96.7%, 98.7% respectively. Type I MSCT showed there were bronchial wall thickening and luminal stenosis, and type II manifested there was involvement of various layers of the trachea, and might no occlusion signs but pneumonia and atelectasis. Type III showed there were wall thickening and hyperplasia. Type IV showed there were obvious stenosis in bronchial lumen and with occlusion signs. Type V showed there were tracheal ring involvement, luminal stenosis and might no occlusion signs. Type VI manifested as involvement of the main bronchial lumen, with nodules and varying degrees of stenosis. Conclusion The performance of MSCT is various in the different types of bronchial patients, and the MSCT may be considered to check the disease severity, the lesions extent and the disease staging.
