Diffusion-weighted imaging detects the slowing of water mo lecules that occurs during the beforehand(predicate) stages of a stroke. It measures the net movement of water molecules in the body repayable to thermal energy (Brownian motion...If you pauperism to get a effective essay, order it on our website: BestEssayCheap.com
