CT对肺结核的诊断价值

目的 探讨CT对肺结核的诊断价值。方法 对比分析40例资料齐全的肺结核患者的胸部正侧位片及CT表现。结果 （1）肺结核病变主要分布在上叶尖后段及下叶背段，其次为上叶前段和下叶各段。（2）胸部CT对肺内隐蔽部位的结核病变显示率明显高于常规胸部X线片检查。（3）胸部CT对病灶内的钙化、纵隔内肿大的淋巴结以及病变的鉴别诊断明显优于胸部X线片检查。结论 胸部CT对肺结核的诊断具有较高的价值。

Study on diagnosis of pulmonary tuberculosis with CT

Objective To determine the diagnostic value of CT in pulmonary tuberculosis. Methods Chest PA & LAT X-ray and CT film image of 40 pulmonary tuberculosis patients with complete information were collected and analyzed. Results (1)Most of intrapulmonary lesions located in superior lobe apicoposterior segment and lower lobe dorsal segment,next ones located in superior lobe anterior segment and lower lobe basal segment. (2)The show rate of the lesions on chest CT films was significantly higher than that of X-ray films. (3)The show rates of focal calcification, inner-mediastinum lymph node enlargement and inner-mediastinum lymph node calcification in chest CT films were significantly higher than that of X-ray films. Conclusion Image of chest CT can provide valuable evidence for diagnosis of pulmonary tuberculosis.
