WebApr 23, 2009 · This could cause oligemic, or even potentially normally perfused but autoregulated tissue, to be recruited into the penumbra and eventually into the final infarct. This vicious cycle may in turn lead to massive infarction and thus to further increases in intracranial pressure and death from herniation. WebThe distinction of small airways disease from primary vascular disease requires the use of paired inspiratory/expiratory CT scans. The terms "mosaic perfusion" or "mosaic oligemia" have also been used to describe this heterogeneous pattern of lung attenuation.
WebPerfusion CT featured specific patterns with respect to patient outcome, with normal brain perfusion or hyperemia in patients with favorable outcome, and oligemia in patients with unfavorable outcome. The number of arterial territories with low regional cerebral blood volume at perfusion CT was an independent prognostic factor (P =.008), as ...
