Abstract
Arterial spin labeling (ASL) is a magnetic resonance imaging perfusion technique that enables quantification of cerebral blood flow (CBF) without the use of intravenous gadolinium contrast. An understanding of the technical basis of ASL and physiologic variations in perfusion are important for recognizing normal variants and artifacts. Pathologic variations in perfusion can be seen in a number of disorders including acute and chronic ischemia, vasculopathy, vascular malformations, tumors, trauma, infection/inflammation, epilepsy and dementia.
