41例严重急性呼吸综合征(SARS)病例X线征象分析

目的:回顾性分析41例SARS病例发病过程中胸部X线平片表现的变化过程,探讨SARS疾病在X线影像学上的特点。方法:按照《广东省SARS病例临床诊断标准(草案)》筛选出我院收治的41例确诊SARS病例,对其发病前后胸部X线平片表现的变化进行分析总结。结果:SARS胸部X线表现以肺内大面积明显浸润为多见(85.4%,35/41),可见于单侧肺(56.1%,23/41)或双肺(43.9%,18/41)。双肺病灶出现及发展可不平衡,病灶变化快。SARS影像表现可分为出现期、加重期和吸收期。结论:SARS虽然特征性胸部X线表现较少,但还是有一定的规律可循,可以为临床提供有价值的早期预警诊断。

Analyzing the chest X-ray images of 41 cases with SARS

Objective:To review and analyze the chest radiographs of 41cases with severe acute respiratory syndrome (SARS),and evaluate the progression of the radiographic appearances during the course of the disease.Meth ods:According to THE GUANGDONG CLINICAL DIAGNOSTIC STANDARDS OF SARS (first draft),41cases with SARS in our hospital were included in this study,an analysis of the developing radiographic features by comparing the initial radiographs and the se-rial radiographs during the course of the disease.Re sults:Large area of infiltration is common on chest radiographs of SARS (85.4%,35?41).The infiltration can appear on either one side(56.1%,23?41)or both sides(3.9%,18?41)of the lung.The ap-pearing and development of changes on both sides of the lung can be unbalanced,and rapid.The radiographic appearance of SARS can be divided into three stages:initial stage with appearance of lesions;stage of radiographic deterioration;stage of le-sion resolving on radiographs.Conclu sion:Though there is no characteristic radiographic features of SARS,but there still have some rules to obey.Radiology plays a central role in diagnosis and follow up of the patients.Radiologists should be aware of the radiographic appearances of this disease so as to prevent transmission of the disease.
