BACKGROUND
The purpose of this study was to compare diagnostic accuracy by using two types of monitors.
METHODS
Four radiologists with 10 years experience twice interpreted the films of 77 fracture cases by using the ViewSonic P75f+ and BARCO MGD221 monitors, with a time interval of 3 weeks. Each time the radiologists used one type of monitor to interpret the images. The image browser used was the Unisight software provided by Atlastiger Company (Shanghai, China), and interpretation result was analyzed via the LABMRMC software.
RESULTS
In studies of receiver operating characteristics to score the presence or absence of fracture, the results of images interpreted through monochromic monitors showed significant statistical difference compared to those interpreted using the color monitors.
CONCLUSION
A significant difference was observed in the results obtained by using two kinds of monitors. Color monitors cannot serve as substitutes for monochromatic monitors in the process of interpreting computed radiography (CR) images with fractures.
背景
本研究的目的是比较使用两种类型显示器的诊断准确性。
方法
四位具有10年经验的放射科医生使用优派P75f +和巴可MGD221显示器对77例骨折病例的影像进行两次解读，时间间隔为3周。每次放射科医生使用一种类型的显示器来解读图像。使用的图像浏览器是由中国上海阿特拉斯虎公司提供的Unisight软件，并通过LABMRMC软件分析解读结果。
结果
在用于对骨折存在与否进行评分的接受者操作特征研究中，与使用彩色显示器解读的图像结果相比，通过单色显示器解读的图像结果显示出显著的统计学差异。
结论
使用两种显示器获得的结果存在显著差异。在解读有骨折的计算机X线摄影（CR）图像过程中，彩色显示器不能替代单色显示器。
