SARS的X线胸片与CT影像学分析

目的 提高对SARS的X线胸片及CT表现的认识 方法 对临床诊断SARS有完整临床及影像学资料的89例进行回顾性分析。 结果 89名患者均高热(100％),>39℃占总数52％男性48例,女性41例,医务工作者8例年龄6～78岁、所有患者均有系列胸片,胸片阴性做CT发现病灶6例、治疗期CT检查16例,X线胸片及CT表现为双肺纹理粗乱,小斑片、硬币样渗出性病变,磨玻璃样病变。病灶变化快,可在2～3天内快速融合实变,病变可呈单病灶或多病灶。出院后复查做CT检查2例,显示肺纤维索条影。 结论 SARS肺部影像学特点为多发性、多形性、多变性、游走快,既三多一快。肺部阴影可以完全吸收消散,肺损伤持续时间长.少数病人可出现肺纤维化

Preliminary analyze with roentgenographic and CT appearance in patients with severe acute respiratory syndrome

Objective To improve recognition for the appearance and dynamic change of chest roentgenographv and CT. Methods Eighty-nine patients with SARS confirmed by clinical manifestations, laboratory investigation and roentgenolgy were retrospective analyzed. Results The patients were consisted of 48 men and 41women, aged from 6-78 years including 8 infected health-care professionals with fever in all ones,over 39t in 52% of patients. All patients have a serial roentgenography and CT. In the early phase of SARS patients roentgenog-raphy of 6 case were normal appearance when they were abnormal on CT. Sixteen examined on CT in treatment phase .The major radiograph-ic signs of chest roetgenograpgic findings showed granular,single or bilateral localized patch, reticulated, coin-like appearance, opacity-glass sign, which progressed rapidly into hardgraphic in 2-3days, 2 cases in the recovery phase out-hospital performed CT scanning showed lung fibrosis. Conclusion Feature of several signs,variety shape and progressed rapidly are showed on X-ray and CT in patient with severe acute respiratory syndrome (SARS). The pulmonary opacity of SARS may completely disappear. Lung appearance are lasted during a long time. Lung fibrosis can be found in few patients.
