下肺结核的X线诊断

X-ray Diagnosis of Pulmonary Tuberculosis in Lower Fields

目的:探讨下肺结核的X线表现,旨在提高正确诊断率。方法:回顾性分析60例下肺结核X线胸片表现,其中27例同时有CT扫描。结果:根据X线表现可分为肺炎型、结节型、纤维增殖型及孤立空洞型。结论:下肺结核X线表现不典型,多发病灶、支气管壁增厚、腔狭窄及腺泡结节为较特征的表现,胸片结合CT扫描有助于诊断和鉴别诊断,特别是HRCT可判断病灶的活动性。

Objective To evaluate the diagnostic value of the chest X-ray and CT examination of pulmonary tuberculosis in lower field. Methods The X-ray findings of 60 pulmonary tuberculosis in lower field cases while 27 cases had CT scans simultaneously were retrospectively analyzed. Results According to the X-ray findings of pulmonary tuberculosis in lower fieldwere categorized to four types：pneumonia lesion;nodule lesion; fibrotic and proliferative lesion; singal cav- itation lesion. Conclusion The pulmonary tuberculosis in lower field were not typital, multiple lesions, wall thickening of bronchia stricture of bronchia and lobuar nodule were characteristic findings, chest radiographs combined with CT is helpful in the diagnosis and differential diagnosis, HRCT can judge lesions activily.
