深吸气薄层肺CT扫描所见不均一的衰减可由肺部浸润性疾病(毛玻璃样改变)、气道阻塞性疾病(斑片状阴影)或血管阻塞(斑片状阴影)引起。为评价呼气扫描对不同原因导致的肺不均一衰减性病变的诊断价值,作者自299例诊断或疑诊为弥漫性肺实质变性的患者中,除外肺实变、肺气肿、纤维化或蜂窝样改变,选择吸气CT扫描主要表现为肺不均一衰减的病人53例,男性20例,女性33例,年龄16～88岁。诊断由肺功能检查结果结合开胸活检、支气管肺泡灌洗术、临床评价及随访等资料确定。其中浸润性疾病26例,气道疾病19例,血管疾病1
Inhalation thin-layer CT scan of lungs seen uneven attenuation may be caused by pulmonary infiltrates (glassy changes), airway obstructive disease (patchy shadows) or vascular obstruction (patchy shadows). In order to evaluate the diagnostic value of breath scan for different causes of non-uniform attenuation of lesions, of 299 patients diagnosed or suspected of being diffuse pulmonary parenchymal degeneration, the authors excluded pulmonary consolidation, emphysema, fibrosis or Honeycomb-like changes, the choice of aspiration CT scans were mainly manifested as uneven attenuation of lung disease in 53 patients, 20 males and 33 females, aged 16 to 88 years. Diagnosis by pulmonary function test results combined with open-chest biopsy, bronchoalveolar lavage, clinical evaluation and follow-up and other data to determine. 26 cases of invasive disease, airway disease in 19 cases, vascular disease 1
