| 目的 探讨胸部CT检查对SARS的诊断价值。方法 临床疑似SARS并同时行常规胸片和CT检查的患者21例。其中男13例,女8例,年龄21~77岁(平均43岁)。所有患者在发病后1周内均行X线胸片和CT扫描,时间间隔1~6h。结果 21例患者中16例胸片表现异常,5例表现正常。16例胸片异常的病例中,11例符合SARS表现,4例肺部阴影为伪影假象(3例肺部CT正常)或其他疾病。5例胸片正常的病例中,有3例CT显示SARS病灶。SARS典型的CT表现为演变迅速的磨玻璃影(100%)和伴有不规则实变或肉芽肿样病变的混合影。结论 X线胸片是SARS早期诊断的首选方法,但当胸片诊断或排除困难时应及时行胸部CT检查。 |

| Objective To evaluate thoracic CT value in diagnosis of SARS.Methods The study comprised 21 patients (13 men, 8 women; age range 21 to 77) suspected SARS. Chest radiograph and CT(interval time of 1~6 hours) were performed in all the patients during the first weeks.Results Plain film showed abnormal findings in 16 patients and normal appearance in 5 patients. The radiographic findings were similar to SARS in 11 patients.The lesions in 4 patients on chest film were proved as artifact shadow and TB focus.Three patients with SARS had normal appearances on chest film. On CT, the most common findings of SARS were rapidly changeful patchy ground-glass opacification (GGO) and mixed lesions of GGO with irregular consolidation and/or granulomas.Conclusion The plain film of the chest is the most common technique for the early diagnosis of SARS. Thoracic CT or follow-up plain film is useful when it is very difficult to diagnose SARS according to the findings on first film. |
