WJ Powers - Annals of neurology, 1991 - interscience.wiley.com During the past decade, technological advances have made it possible to measure regional
cerebral hemodynamics in individual patients. Studies performed with these techniques have
demonstrated that the degree of carotid stenosis correlates poorly with the hemodynamic ... Cited by 469 - Related articles - All 3 versions

WD Heiss - Journal of Cerebral Blood Flow & Metabolism, 2000 - nature.com The ischemic penumbra is defined as tissue with flow within the thresholds for maintenance of
function and of morphologic integrity. Penumbra tissue has the potential for recovery and therefore
