Abstract: Perfusion magnetic resonance (MR) images are often used in the assessment of acute ischemic stroke to distinguish between salvageable tissue and infarcted core. Deconvolution methods such as singular value decomposition have been used to approximate model-based perfusion parameters from these images.

For these reasons, diffusion MR has preceded perfusion MR for widespread use in stroke imaging. Sunshine and colleagues in this issue of AJNR (page 915) find that perfusion MR imaging provides greater accuracy than does diffusion MR imaging for categorizing the vascular distribution of ischemia in patients scanned within 6 hours of ischemic onset. Usually a lacune, if its a stroke at all. Cortical branch (“large” or “medium” size vessel) occlusion is not suspected, so an MR is done a few hours later. The result is an awesome example of what hyperacute stroke looks like on MRI, MRA, and MR perfusion. Diffusion shows a small right opercular lesion Dedicated stroke MR imaging protocols have been established and include DWI and PWI as well as MRA of the intra- and extracranial vessels.
