This largely stems from the initial popularisation of DWI in stroke, which presented infarcted tissue as high signal on isotropic maps and described it merely as "restricted diffusion", implying that the rest of the brain did not demonstrate restricted diffusion, which is clearly not true.
#Fluid image techniques how to#
a more general term to encompass all diffusion techniques including diffusion tensor imagingĪdditionally, confusion also exists in how to refer to abnormal restricted diffusion.
the pulse sequence that results in the generation of the various images (e.g.isotropic diffusion map (what most radiologists and clinicians will refer to as DWI).The first problem is that the term "diffusion-weighted imaging" is used to denote a number of different things: 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.
