目的 探讨重型严重急性呼吸综合征 (SARS)的胸部X线表现。方法 回顾性分析36例重型SARS胸部X线表现 ,并与 2 2 4例普通型SARS做对比分析。结果 36例重型SARS胸部X线表现与 2 2 4例普通型SARS比较 ,显示肺内大片状影 (P <0 0 1)、大范围实变 (P <0 0 1)、磨玻璃样改变 (P <0 0 1)、弥漫性病变 (P <0 0 1)、双肺受累 (P <0 0 1)这 5种X线表现在两组病例间差异具有非常显著性意义。结论 大片状影、大范围肺实变、磨玻璃样改变、弥漫性病变、双肺受累是诊断重型SARS的主要X线表现。
Objective To investigate the chest X-ray findings of Severe Severe Acute Respiratory Syndrome (SARS). Methods Thorax X-ray findings of 36 cases of severe acute respiratory syndrome (SARS) were retrospectively analyzed and compared with 224 cases of common type SARS. Results Thoracic X-ray findings of 36 severe SARS patients were compared with 224 normal SARS patients, showing large patchy lungs (P <0.01), extensive consolidation (P <0.01), ground glass changes (P <0.01), diffuse lesions (P <0.01), and bilateral lung involvement (P <0.01). There were significant differences between the two groups in the five X-ray findings. Conclusions The large radiographs, extensive lung consolidation, ground glass-like changes, diffuse lesions and bilateral lung involvement are the main radiological findings in the diagnosis of severe SARS.
