This study compared an 8MP vs dual-5MP displays for diagnostic accuracy, reading time, number of times readers zoomed/panned images, and visual search. Six radiologists viewed 60 mammographic cases, once on each display, 15 with eye-tracking. For viewing time, there was significant difference (F = 13.901, p = 0.0002), with 8MP taking less time (62.04 sec vs 68.99). There was no significant difference (F = 0.254, p = 0.6145) in zoom/pan use (1.94 vs 1.89). Total number of fixations was significantly (F = 4.073, p = 0.0466) lower with 8MP (134.47 vs 154.29). Number of times readers scanned between images was significantly fewer (F = 10.305, p = 0.0018) with single (6.83 vs 8.22). Time to first fixate lesion did not differ (F = 0.126, p = 0.7240). It did not take any longer to detect the lesion as a function of the display configuration. Total time spent on lesion did not differ (F = 0.097, p = 0.7567) (8.59 vs 8.39). Overall the single 8MP display yielded the same diagnostic accuracy as the dual 5MP displays. The lower resolution did not appear to influence the readers' ability to detect and view the lesion details, as the eye-position study showed no differences in time to first fixate or total time on the lesions. Nor did the lower resolution result in significant differences in the amount of zooming and panning that the readers did while viewing the cases.
