1 results about "Arterial spin labeling" patented technology

Arterial spin labeling (ASL), also known as arterial spin tagging, is a magnetic resonance imaging technique used to quantify cerebral blood perfusion by labelling blood water as it flows throughout the brain. ASL specifically refers to magnetic labeling of arterial blood below the imaging slab, without the need of gadolinium contrast, which is the first of its kind in terms of perfusion imaging.
