摘要
目的探讨胸部X线影像图像质量评定标准与肺部病灶检出率的相关性.方法选取本院2016年10月至2018年10月期间收治的60例肺炎患者为对象,基于不同摄影条件、病灶大小和感兴趣区域对患者实施胸部X线摄影并出具直接数字化X线摄影(DR)图像.依据不同标准对患者的DR图像进行质量评价,将解剖学标准分析结果作为A组数据,物理学标准分析结果作为B组数据,临床病灶检出率诊断的分析结果作为C组数据,采用Spearman相关性分析对A组、B组及C组数据进行一致性检验.结果15 mm和10 mm病灶图像的相关系数r值均>0.8;5 mm病灶图像的相关系数r<0.8,相关关系并不密切.结论解剖学标准和物理学标准是DR胸部图像质量评价工作的重要依据,15 mm和10 mm病灶图像肺部病灶检出率越高,5 mm病灶推荐使用其他影像检查方法.
Objective To investigate the correlation between the quality evaluation criteria of chest X-ray images and the detection rate of pulmonary lesions.Methods Sixty patients with pneumonia admitted to our hospital from October 2016 to October 2018 were selected as the subjects.Chest X-ray photography and DR images were performed based on different photographic conditions,lesion size and region of interest.The quality of DR images was evaluated according to different standards.The results of anatomical standard analysis were taken as group A data,physical standard analysis as group B data,and the results of diagnosis of clinical lesions as group C data.The consistency of data of group A,group B and group C was tested by Spearman correlation analysis.Results The correlation coefficients of 15 mm and 10 mm lesion images were all higher than 0.8,while the correlation coefficients of 5 mm lesion images were lower than 0.8.Conclusion Anatomical and physical criteria are important criteria for evaluating the quality of DR thoracic images.The higher the detection rate of pulmonary lesions in 15 mm and 10 mm lesions,the better the detection rate of pulmonary lesions in 5 mm lesions.
