A great deal of confusion exists in the way the clinicians and radiologists refer to diffusion restriction, with both groups often appearing to not actually understand what they are referring to. The first problem is that the term "diffusion-weighted imaging" is used to denote a number of different things: 1. … See more As opposed to essentially free diffusion of water kept inside a container, diffusion of water inside brain tissue, for example, is hindered primarily by cell membrane boundaries. The overall diffusion characteristics of a … See more Diffusion-weighted imaging has a major role in the following clinical situations 3-5: 1. early identification of ischemic stroke 2. differentiation of … See more A variety of techniques for generating diffusion maps have been developed. By far the most commonly used technique relies on a spin-echo echo-planar sequence (SE-EPI) … See more WebJul 15, 2024 · Diffusion-weighted imaging (DWI) is a commonly performed MRI sequence for the evaluation of acute ischaemic stroke and is very sensitive in the detection of small and early infarcts . Conventional MRI sequences (T1WI, T2WI) may not demonstrate an infarct for 6 hours, and small infarcts may be hard to appreciate on CT for days, …
