SARS的X线胸片与CT影像学分析

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

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.

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.
