目的 研究SARS患者不同阶段的临床与影像学改变。方法 对 12 3例住院患者进行影像与临床分析。结果 影像改变 :早期 ,病灶多发或单发 ,表现多种多样 ,肺实质改变不明显 ;进展期 ,病变迅速发展 ,范围扩大 ,病灶数目明显增多 ,影像表现呈多样性 ;吸收期 ,病灶明显缩小、变淡 ,部分有纤维化表现。胸部CR、DR与HRCT影像学表现相似 ,但HRCT更敏感。临床表现 :早期 ,发热、全身及关节酸痛 ,咳嗽 ,白细胞正常或偏低 ;进展期 ,在上述症状加重的基础上出现血氧饱和度下降 ,有 2 0 %的患者发展为ARDS ;恢复期 ,80 %的患者好转康复出院。结论 SARS的影像表现与其它肺炎相似 ,特异性不强 ,肺部病变的变化与临床表现无明显相关性。但是影像学仍是作为治疗、了解病变的重要依据。
Objective To study the clinical and radiographic changes in different stages of SARS patients. Methods We performed imaging and clinical analysis of 123 inpatients. Results The image changes: early, multiple or single lesions, the performance of a variety of lung substantive changes were not obvious; advanced, the rapid development of lesions, the scope of the expansion, the number of lesions increased significantly, the image showed a diversity; absorption period, lesions were significantly reduced , Fades, some have fibrosis. Chest CR, DR and HRCT imaging similar, but HRCT more sensitive. Clinical manifestations: early, fever, systemic and joint pain, cough, normal or low white blood cells; advanced stage, the above symptoms worsen based on the oxygen saturation decreased, 20% of patients developed ARDS; recovery, 80% of patients recovered and discharged. Conclusion The imaging findings of SARS are similar to other pneumonia and the specificity is not strong. There is no significant correlation between the changes of lung lesions and clinical manifestations. However, imaging is still an important basis for treatment and understanding of the disease.
