目的 :探讨普通型SARS的胸部X线表现。方法 :回顾性分析 2 2 4例普通型SARS病人的胸部X线表现 ,并与 3 6例重型病例作对比分析。结果 :2 2 4例普通型SARS胸部X线表现显示 :斑片状影 15 6例 (69 64 % )、大片状影 80例 (3 5 71% )、间质改变 182例 (81 2 5 % )、磨砂玻璃样改变 85例 (3 7 95 % )、片状影内见支气管气像 178例 (79 46% )、大范围肺实变 2 1例 (9 3 8% )、单肺受累 80例 (3 5 71% )、双肺受累 14 4例 (64 2 9% )。结论 :普通型SARS的X线主要表现为斑片状影、间质性改变、片状影内见支气管气像及双肺受累 ,且病变吸收、消散相对较快 Objective: To investigate the chest X-ray findings of common type SARS. Methods: A retrospective analysis of 224 cases of SARS patients with chest X-ray findings, and 36 cases of severe cases for comparative analysis. Results: Chest X-ray findings of 224 cases of common type SARS showed that there were 156 cases (69 64%) of patchy images, 80 cases (35 71%) of large patchy films and 182 cases of interstitial changes (81 2 5 85% (3 7 95%) of the frosted glass samples, 178 (79 46%) bronchial images within the patchy shadow, and 21 (19.38%) cases of the large area pulmonary solidification Eighty patients (35 71%) and 14 4 patients (64 2 9%) had bilateral lung involvement. Conclusion: X-ray of common type SARS mainly showed patchy shadow and interstitial changes. Bronchial airway and bilateral lung involvement were seen in patchy shadow, and the lesions were absorbed and dissipated relatively fast
