【摘要】：目的:探讨在胸片拍摄中采用计算机X线摄影(CR)与直接数字化X线摄影(DR)的质量比较。方法:将我院2013年10月-2015年10月接受胸片检查的患者400例选为研究对象,依据胸片拍摄方式划分为两组,其中CR组与DR组各200例,对比两组胸片图像质量。结果 :CR组5.5%为甲级片,92.5%为乙级片,2.0%为废片;DR组15.0%为甲级片,85.0%为乙级片,无废片,两组甲级片率对比差异明显(P0.05);CR组合格率为95.0%,10张因IP板出现扫描故障而重拍,DR组合格率为100.0%,对比无明显差异(P0.05)。结论:当前拍摄胸片图像主要应用CR与DR,二者有其共性,但是DR图像质量更优,几乎无重拍现象,便于临床诊断,值得推广。
[Abstract]:Objective: to compare the quality of computed radiography (CR) and direct digital radiography (Dr) in chest radiography. Methods: 400 patients who received chest radiographs from October 2013 to October 2015 were divided into two groups according to the mode of chest radiography, 200 cases in CR group and 200 cases in Dr group. The quality of chest radiography was compared between the two groups. Results in the control group, 95% of them were grade A tablets, 92.5% were grade B tablets, 2.0% were waste tablets, 15.0% were grade A tablets, 85.0% were grade A tablets, and there were no scrap tablets. There was significant difference between the two groups (P0.05) the qualified rate of CR group was 95.0% and the eligible rate of rebeat Dr group was 100.0because of IP board scanning fault. There was no significant difference between the two groups (P0.05). Conclusion: CR and DR2 are mainly used in chest radiography at present, but the quality of Dr images is better and there is almost no reshoot phenomenon, which is easy to diagnose and worth popularizing.
