目的 比较分析严重急性呼吸综合征(SARS)不同年龄组的X线征象。资料与方法 回顾性分析临床诊断的179例SARS患者胸片,患者分为<30岁,30～50岁,>50岁3组,比较分析不同年龄组之间病灶部位、范围、数量、形态、密度和均匀度、边缘和境界、以及肺内基础病变,并进行统计学分析。结果 不同年龄组X线征象的相同点:病灶呈斑片状,密度不均匀的略高密度,边缘模糊不清,多累及两肺,肺中野中带最为常见;不同点为:<30岁组和30～50岁组右肺受累多于左肺,病灶局限,数量少于>50岁组;而>50岁组的病灶多数呈多发片状,累及多个肺区,而且多合并肺内基础病变。结论 SARS不同年龄组之间的X线征象既有相同点,又有一定差异,分析X线征象对临床和科研有重要意义。
Objective To compare and analyze the X-ray findings of different age groups of severe acute respiratory syndrome (SARS). Materials and Methods Retrospective analysis of the clinical diagnosis of 179 cases of SARS patients chest radiography, patients were divided into three groups of <30 years old, 30 to 50 years old,> 50 years old, the comparative analysis of different age groups lesions location, range, number, Density and uniformity, margins and realms, as well as the underlying lung lesions, and statistical analysis. Results The similarities of X-ray signs in different age groups were as follows: the lesions were patchy, the density was slightly high, the edges were blurred, And 30 to 50-year-old group more than the right lung lung involvement, lesions limited, the number of less than> 50-year-old group; and> 50-year-old group lesions were multiple flake, involving multiple lung areas, Lesions. Conclusion The X-ray signs of different age groups in SARS have similarities and differences, and the analysis of X-ray signs is of great significance for clinical and scientific research.
