Making sense of ASL and BOLD brain scans

Arterial spin labeling (ASL) and blood oxygen level–dependent (BOLD) imaging are two MRI methods that reveal different aspects of brain activity and blood flow. BOLD is widely used for functional ...

Cerebral Blood Flow Imaging Using Arterial Spin Labeling

Arterial spin labeling (ASL) is a non‐invasive magnetic resonance imaging technique that exploits magnetically labelled arterial blood water as an endogenous tracer to quantitatively assess cerebral ...
