Corrected measured ADC deviations (dADC_corr) over the cardiac cycle for gray matter (blue) and white matter (red). Results were obtained by subtracting simulated dADC induced by tissue deformation from measured dADC. Because the measured dADC deviations were on average 2.2 ± 1.1 (gray matter) and 2.6 ± 0.82 (white matter) times larger than simulated deviations, dADC_corr is still of the same order of magnitude as the measured dADCs (see Figure 5). These corrected ADC deviations from the mean ADC cannot be explained by intrinsic artificial signal variations arising from tissue deformation
