Can the Ischemic Penumbra Be Identified on Noncontrast CT of Acute Stroke?
Storke 38:2485-2490, Muir,K.W.,et al, 2007
See this aricle in Pubmed
Article Abstract
Regions exhibiting hypoattenuation are likely to represent the infarct core, whereas regions that are isodense and swollen have increased cerebral blood volume and are more likely to signify penumbral perfusion. Although noncontrast CT is not sensitive for detection of core and penumbra, appearances are specific. Some information on tissue viability can therefore be obtained from noncontrast CT.
