摘　　要：目的　探讨严重急性呼吸综合征 (SARS)的计算机 X线摄影 (Com puter Radiograph CR)影像学表现。　方法　对已确诊的 18例严重急性呼吸综合征患者的胸部影像学特征进行回顾性分析。　结果　 SARS的影像学表现不尽相同 ,主要显示为肺实质和肺间质渗出性病变两大征象 ,病变早期 X线表现多为肺野外带或以胸膜为基底的毛玻璃状阴影、明显实变阴影或结节状阴影是唯一异常表现 ,病情恶化患者的肺部浸润阴影表现为实变范围进一步扩大 ,病灶相互融合呈单侧或两侧大范围实变 ,边缘模糊 ,少数病例其病灶有游走现象。　结论　胸部计算机 X线摄影影像检查 (CR)由于具有较高的清晰度 ,是发现 SARS的理想的影像学检查方法 ,在 SARS的诊治过程中 ,了解和掌握本病的影像学特征 ,对判断病情 ,指导治疗 ,评估预后具有重要的指导意义。Objective To explore chest computer radiographic appearances of Severe Acute Respiratory Syndrome (SARS). Methods Computer radiograph findings of 18 patients with SARS were retrospectively analyzed. All the patients had a complete set of chest film and clinical data. Result Computer radiograph findings of SARS were various and appeared dominantly as two types that are the parenchymal and interstitial exudation. Chest computer radiograph demonstrated the mottling or patchy opacity and frosted-glass form shadow in both sided lung in the earlier period. The condition worsens the sufferer's lung gradually the shadow performance is a solid changing the scope to further extend, edge misty and focus roves around the lung in the few patients. Conclusion Computer radiography is provided with higher definition, was an elementary imaging means of choice for detecting with SARS. It is necessary to study radiological types and stages of SARS in the diagnostic and therapeutic procedure, which is helpful to assessing the disease condition, planning the therapy and evaluating the prognosis.
