Preliminary analysis of clinical images of SARS

目的 总结SARS患者的临床及胸部影像学资料 ,以期提高对这一烈性传染病的认识。方法 回顾性分析 175例临床诊断SARS患者的临床和影像学资料。 175例患者共摄胸片 10 60张 ,行CT扫描 2 0例次。结果 SARS的典型影像学表现为双侧或单侧多叶、多片的肺实质浸润 ,共 97例( 59 .5% ) ,61例 ( 3 7.4% )为局限性单侧肺浸润。以快速进展变化为特征 ;病死率为 8.0 %。结论胸部影像异常是SARS诊断的必要指标 ,系列X线平片可以观察SARS的病情变化 ,指导治疗并提示预后 。

Objective To investigate the clinical thoracic images of SARS. Methods Thoracic images of SARS were analyzed in 175 patients with 1 060 chest plain films and 20 CT scans. Results The typical signs of SARS were multifocal air-space consolidations and progress over a day from small shadow to generalized findings.
