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 ,CT能够早期检出SARS肺部的异常征象
Objective To summarize the clinical and thoracic imaging data of SARS patients with a view to raising awareness of this potent infectious disease. Methods The clinical and imaging data of 175 patients with clinically diagnosed SARS were retrospectively analyzed. A total of 175 patients with a total of 10 60 chest radiography, CT scan line 20 times. Results The typical radiological features of SARS were bilateral or unilateral multilobular and multiple pulmonary infiltrates, 97 cases (59.5%) and 61 (37.4%) with localized unilateral pulmonary infiltrates. Characterized by rapid progression; mortality was 8.0%. Conclusions Chest imaging abnormalities are necessary indicators for the diagnosis of SARS. The series of X-ray films can observe the changes of SARS, guide the treatment and prognosis, and CT can detect the abnormal signs of SARS in the early stage
