Effect of intravenous dipyridamole on cerebral blood flow in humans. A PET study.

abstract：BACKGROUND AND PURPOSE:Brain atrophy, cortical infarction, and subcortical ischemic vasculopathy have all been associated with cognitive dysfunction. The interrelationships between these pathologies and their independent contributions to cognitive function remain unclear. Despite the high frequency of Alzheimer disease...
