肺实质炎性细胞浸润或肺泡炎可以导致间质性肺病变(interstitial lung disease,ILD)甚至肺纤维化,为了预防肺纤维化,有必要对活动期的 ILD 进行治疗。常规 X 线摄片、肺功能和血气分析等检查缺乏特异性和敏感性,不能鉴别 ILD 的活动性。作者报告应用磁共振成象(MRI)对 ILD 活动性的研究结果。34例 ILD,男15例,女19例,年龄24～82(平均58.6)岁。诊断为隐源性致纤维化肺泡炎(CFA)19例、肺肉瘤6例、药物性肺泡炎2例、肺孢子虫1例、外源性过敏性肺泡炎(EAA)1例、淋巴样间质性肺炎(LIP)1例、肺嗜酸性肉芽肿(EGL)1例、进行性系统性硬化症1例、原因不明2例。12例行开胸
Pulmonary parenchymal inflammatory cell infiltration or alveolitis can lead to interstitial lung disease (ILD) and even pulmonary fibrosis. In order to prevent pulmonary fibrosis, it is necessary to treat the active ILD. Routine X-ray, pulmonary function tests and blood gas analysis lack of specificity and sensitivity, can not identify the activity of ILD. The authors report the results of magnetic resonance imaging (MRI) studies of ILD activity. 34 cases of ILD, 15 males and 19 females, aged from 24 to 82 (mean 58.6) years. 19 cases of cryptogenic alveolar fibrosis (CFA), 6 cases of pulmonary sarcoma, 2 cases of drug-induced alveolitis, 1 case of pneumocystosis, 1 case of exogenous allergic alveolitis (EAA), 1 case of lymphoid interstitial 1 case of proto-pneumonia (LIP), 1 case of pulmonary eosinophilic granuloma (EGL), 1 case of progressive systemic sclerosis, 2 cases of unknown cause. Thirteen patients underwent thoracotomy
