目的探讨不同数字化胸片(DR)处理参数对接尘者数字化X线胸片图像的影响.方法对105例粉尘作业人员,同时拍摄高仟伏X线胸片和DR,用DR常规处理法和职业病特殊要求处理法设置不同的图像处理参数.参照高仟伏胸片分别对10个解剖部位的显示情况进行评分,比较DR常规处理法和职业病特殊要求处理法处理DR图像的差异,并与高仟伏胸片进行比较.结果 DR常规处理法处理DR图像10个解剖部位的评分大部分集中于0和+1水平,二者共占88％以上,评分均值在0.23～0.65之间,DR图像评分均值与高仟伏图像评分的差异有明显统计学意义(P＜0.01)；职业病特殊要求处理法处理DR图像10个解剖部位的评分大部分集中于0,可占65％以上.除“胸膜胸壁”外,评分均值在-0.01 ～+0.02之间,DR图像评分均值与高仟伏图像评分的差异无统计学意义(P＞0.05).经DR常规处理法和职业病特殊要求处理法处理的DR图像的1 0个解剖部位评分的差异均有统计学意义(P＜0.01).结论不同处理参数得到的DR图像不同,经职业病特殊要求处理法处理的DR图像对解剖部位的显示基本等同于高仟伏胸片.

Objective To investigate the effect of different processing parameters of digital radiography (DR) on the image quality of digital chest radiograph in dust-exposed workers.Methods One hundred and five dust-exposed workers underwent both high-KV radiography and DR to obtain chest radiographs; the image processing parameters were set by the conventional processing method for digital chest radiograph (method A) and the processing method based on the special requirements of occupational diseases (method B).With the high-KV chest radiograph as the reference,the image qualities at 10 anatomic sites of DR image were graded.The images acquired by DR and high-KV radiography were compared,and the DR images acquired by methods A and B were also compared.Results For method A,the scores at the 10 anatomic sites of DR image were mostly 0 and +1,accounting for over 88％,and the mean score was 0.23～0.65,there was a significant difference between the mean score of DR image and the score of high-KV image (P＜0.001).For method B,the scores at the 10 anatomic sites of DR image were mostly 0,accounting for over 65％,and the mean score was -0.01～+0.02 except at the pleura and chest wall; there was no significant difference between the mean score of DR image and the score of high-KV image (P＞0.05).There were significant differences in the scores at the 10 anatomic sites between the DR images acquired by methods A and B (P＜0.01).Conclusion The DR images acquired based on different processing parameters are different.The quality of DR image acquired by the processing method based on the special requirements of occupational diseases is similar to that of high-KV image at the anatomic sites.
