Arterial spin labeling (ASL) is a magnetic resonance imaging technique for measuring cerebral blood flow. Recent advancements have expanded its clinical applications and improved its utility in both research and daily medical practice.

Area of Science:

  • Medical Imaging
  • Neuroscience
  • Biophysics

Background:

  • Arterial spin labeling (ASL) is a non-invasive magnetic resonance imaging (MRI) technique.
  • It measures cerebral blood flow (CBF) by magnetically labeling water molecules in arterial blood.
  • The technique has transitioned from experimental settings to clinical use over the past decade.

Purpose of the Study:

  • To provide a comprehensive review of arterial spin labeling (ASL) techniques.
  • To compare different ASL implementations and summarize their theoretical underpinnings.
  • To propose potential applications of ASL in clinical practice and research.

Main Methods:

  • Review of existing literature on ASL.
  • Comparison of various ASL pulse sequence implementations.
