Conference paper


The results of recent experimental studies using animal models have greatly increased our knowledge of the early biochemical, pathophysiological, and histological events in ischemic brain tissue damage [1–7]. To improve the clinical results of early intervention in acute stroke patients, it is important that clinical practice respond to the implications of the results obtained in experimental studies [8,9]. Positron emission tomography (PET) of the brain provides quantitative maps of regional cerebral blood flow, oxygen metabolism, and blood volume. Although PET has some limitations, it may provide a bridge between experimental studies and clinical practice. In this symposium, we present our experiences with PET studies in patients with cerebral embolism in the very acute phase and discuss indication for reperfusion treatment.
