The authors investigate the effect of image processing on diagnostic performance in the reading of computed chest radiographs.
Six radiologists read 168 chest images with and without the use of image processing. Diagnostic performance was measured by means of receiver operating characteristic analysis, and changes made in diagnostic decisions with the use of image processing were evaluated.
There were no statistically significant differences between reader performance with image processing and reader performance without image processing (P < .05). Readers' decisions were just as likely to change from false-negative to true-positive as from true-positive to false-negative with the use of image processing. More decisions changed from true-negative to false-positive than from false-positive to true-negative with processing,
The effect of image processing does not greatly influence diagnostic performance in chest radiography.
作者研究图像处理对胸部计算机X线片阅读诊断性能的影响。
六位放射科医生阅读了168张胸部图像，其中部分使用了图像处理，部分未使用。通过接受者操作特征分析来衡量诊断性能，并评估使用图像处理后诊断决策的变化。
使用图像处理时读者的表现与不使用图像处理时读者的表现之间没有统计学上的显著差异（P <.05）。使用图像处理时，读者的决策从假阴性变为真阳性的可能性与从真阳性变为假阴性的可能性相同。与处理后从假阳性变为真阴性相比，更多的决策从真阴性变为假阳性。
图像处理的效果对胸部X线摄影的诊断性能影响不大。
