Claim One:
1. A non-transitory applications program for execution on a computer, the non-transitory applications program for processing magnetic resonance image data acquired using a phase-contrast MRI scan technique to assess vascular reactivity during an arterial occlusion, said non-transitory application program comprises instructions, criteria and code segments for: (a) finding a center of the arterial cross-section being imaged using one of an MRI magnitude image or an MRI phase image of the phase contrast MRI scan; (b) fitting a parabolic curve using selected data of the MRI phase image; (c) using an equation of the fitted parabolic curve to measure shear rate; and (d) calculating a radius of the arterial cross-section using one of the MRI magnitude image or the MRI phase image.
