Diffusion-weighted imaging Radiology Reference Article - Radiopaedia

Diffusion-weighted imaging (DWI) is a form of MR imaging based upon measuring the random Brownian motion of water molecules within a voxel of tissue. In general simplified terms, highly cellular tissues or those with cellular swelling exhibit lower diffusion coefficients. See more 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 … 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 … 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) although non-EPI techniques (e.g. … 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 acute from chronic stroke 3. differentiation of acute stroke from other stroke mimics 4. … See more http://www.duivsdwi.org/ foam t45 helmet template https://annapolisartshop.com
