11 MR perfusion abnormalities have also been described in other disorders, (eg, seizures, … Magnetic resonance (MR) perfusion imaging offers the potential for measuring brain perfusion in acute stroke patients, at a time when treatment decisions based on these measurements may affect outcomes dramatically. Rapid advancements in both acute stroke therapy and perfusion imaging techniques have resulted in continuing redefinition of the role that perfusion imaging should play in patient 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.

Patients were scanned within seven days of symptom onset using the quantitative MRI perfusion protocol (between September 2005 and February 2007) (Table 1). Patients with acute stroke treated with intravenous tPA 3-6 hours after stroke onset: correlations between MR angiography findings and perfusion- and diffusion-weighted imaging in the DEFUSE study The MR imaging protocol for evaluation of stroke, which includes conventional MR imaging, diffusion-weighted imaging, MR angiography, and perfusion-weighted imaging, may take a little longer (15 minutes) (, 66).

Olivot Download Citation | MR perfusion in acute stroke | Magnetic resonance (MR) perfusion provides invaluable insight into the microvascular hemodynamics of acute stroke, allowing identification of APPLICATIONS  MR Perfusion in Stroke  Mismatch between PW and DW represent potentially salvageable tissue (penumbra). PW-DW mismatch is also indicator of clinical outcome. Small mismatch has good clinical outcome.

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.

Perfusion is the passage of fluid through the lymphatic system or blood vessels to an organ or a tissue. The practice of perfusion scanning is the process by which this perfusion can be observed, recorded and quantified. The term perfusion scanning encompasses a wide range of medical imaging modalities.
