Box plot representing the difference between MBFonset and MBFfree from quantification in segmental and voxel-wise analysis in a group of patients. The difference between the obtained MBF values in both normal and ischemic regions of myocardium in voxel-wise analysis (low CNR, CNR = 17 ± 5.2) is higher than found in segmental analysis (high CNR, CNR = 28 ± 3.7). This higher difference proves the sensitivity of voxel-wise analysis to tracer arrival times. No significant difference between the results obtained in segmental analysis with and without using optimized t Onset was observed.
