The impact of MR exposure time sequence was investigated for EBT3 and XD film. As shown above, a high correlation (R > 0.99) was observed regardless of the timing sequences and MR environment between calibration curves for both EBT3 and XD film (a). The percent difference in calculated optical density values was measured at the different dose levels (b)
