Vascular disorders: insights from arterial spin labeling

Area of Science:

• Neuroimaging
• Vascular Neurology
• Medical Physics

Background:

• High-field magnetic resonance imaging (≥3 T) has advanced noninvasive perfusion assessment.
• Arterial Spin Labeling (ASL) is emerging as a clinical tool for evaluating brain blood flow.

Purpose of the Study:

• To evaluate the utility of ASL in assessing perfusion in various cerebrovascular disorders.
• To highlight ASL's role in diagnosing conditions like chronic cerebrovascular disease, stroke, moyamoya disease, and arteriovenous malformations.

Main Methods:

• Utilizing high-field magnetic resonance imaging (≥3 T).
• Employing noninvasive arterial spin labeling (ASL) techniques.
• Integrating territorial imaging of intracerebral arteries and vascular reactivity measurements.

Main Results:

• ASL provides a realistic clinical option for noninvasive perfusion assessment.
• The technique is effective in evaluating vascular diseases of the brain.
• ASL shows potential applications beyond stroke, including moyamoya disease and vascular dementia.

Conclusions:

• Arterial Spin Labeling is a powerful tool for evaluating brain vascular diseases.
• Its integration with advanced imaging techniques enhances diagnostic capabilities.
• ASL holds promise for broader clinical applications in neurology and neuroimaging.
