Absolute quantification of myocardial perfusion is commonly based on a region-of-interest (ROI) analysis in order to achieve a sufficient signal to noise ratio (SNR). 3 T scanners provide the opportunity to acquire dynamic contrast enhanced MRI with higher SNR compared to 1.5 T. This, in turn, may help to absolutely quantify myocardial perfusion not only in ROIs but in every acquired voxel. This study presents first results of a voxelwise myocardial perfusion quantification.
