Arterial spin labeling (ASL) and intravoxel
incoherent motion (IVIM) are both noninvasive MRI techniques that offer
quantitative perfusion measurements. The current study showed that the ASL perfusion decreased while the IVIM vascular volume fraction increased compared to baseline under cuff compression paradigm in the lower extremity muscle, indicating that the two MRI techniques based on two completely distinct mechanisms provide complementary tissue perfusion characteristics.
