Abstract:
1. A method for providing corrected quantitative results from magnetic resonance imaging (MRI), the method comprising: performing first imaging to provide at least a first blood flow (BF) image, wherein a modality of said first imaging is a modality other than arterial spin labeling (ASL) MRI; performing second imaging to provide at least an ASL BF image corresponding to said first BF image, wherein said second imaging is arterial spin labeling MRI; selecting some voxels of said first BF image according to a predetermined selection method to provide a set of selected voxels; calculating a correction factor CF equal to the ratio of ASL BF image to first BF image averaged over said selected voxels; applying said correction factor to one or more images provided by said first imaging to provide one or more quantitatively corrected images as output; wherein said predetermined selection method comprises selecting voxels that have a Tmax below a predetermined Tmax threshold, wherein the predetermined Tmax threshold is between 2 seconds and 4 seconds.
