Incoherent motion
WebJul 30, 2015 · Under the assumed isotropic and random nature of the microvascular network system resulting in the incoherent motion of water in the blood, both capillary perfusion (D*, f) and true molecular diffusion (D) can be assessed using DWI with multiple b-values. In a pioneering study [4], IVIM was used to quantify perfusion in the human brain. http://web.mit.edu/robertsilbey/research/papers/1991-2000/rsilbey_coherent_incoherent_motion_one-dim_lattice.pdf
