Diffusion-weighted (DW) magnetic resonance (MR) imaging provides potentially unique information on the viability of brain tissue. It provides image contrast that is dependent on the molecular motion of water, which may be substantially altered by disease. The primary application of DW MR imaging has been in brain imaging, mainly because of its exquisite sensitivity to ischemic stroke, a common condition that is very common nowadays.
