摘要

The purpose of this study was to determine if displays that provide more grayscale levels (lObit vs. 8bit) can improve observer performance in breast cancer detection. The study was also designed to determine if 3MP (million-pixel) displays can achieve similar observer performance as compared to 5MP displays. The study was performed using the WorkstationOne mammography software on Dome? E5 and E3 high-resolution displays. Ten radiologists reviewed 33 digital mammography screening studies. On 5MP displays, the average Az value across all observers was 0.7912 using 8bit displays, and 0.8306 using lObit displays. The difference between 8bit and lObit displays is statistically significant (F=4.43, p=0.0157). The difference of the average Az value from 8bit 3MP displays is not statistically significant compared to reading with 5MP displays. The implications of the study are that, using appropriate software and hardware, 5MP lObit displays may improve diagnostic accuracy and 3MP displays may not impact negatively diagnostic accuracy.
