【摘要】 目的:分析例下肺野结核的与线表现,减少误诊。45CTX方法:对例下肺野结核进行常规胸部扫描或线胸45CTX片检查,全部病例均经结核菌阳性或病理证实。结果:下肺野结核的影像学表现主要为渗出性病灶,占,且常伴有增75.5%殖、纤维性病灶。空洞或球形病灶常伴有周围“卫星”灶。对病灶的显示率明显高于线。CTX结论:空洞或球形病灶伴周围“卫星”灶对下肺野结核的诊断价值较大;几种病灶并存是下肺野结核较为特征性表现;密切结合临床,可明显提高正确诊断率。确诊需依靠痰菌阳性或病理。检查较线敏感。CTX更多还原

【Abstract】 Objective: To analyze CT and X-ray manifestations of pulmonary tuberculosis of lower lung field in 45 cases and to reduce misdiagnosis. Methods: Forty-five cases of pulmonary tuberculosis of lower lung field were examined by thoracic CT and chest film. All cases were confirmed by pathology or positive tubercle bacilli. Results: Imaging manifestations of pulmonary tuberculosis of lower lung field were mainly exudative lesions (75.5%)with proliferation and fibrosis. Cavitation or global lesion was commonly associated with surrounding “”satellite lesions. Conclusion: “” Cavitation or global lesion with surrounding satellite lesions is important for the diagnosis of pulmonary tuberculosis in lower lung field. Coexistence of different kinds of lesions was a characteristic finding of the disease. The combination of imaging appearance with clinical information can reduce misdiagnosis. The final diagnosis depends on pathology or positive tubercle bacilli. CT is more sensitive than X-ray.更多还原
