Evaluating Vascular Hemodynamics in Cerebral Proliferative Angiopathy Using Advanced Arterial Spin Labeling MRI

Stroke: Vascular and Interventional Neurology
Cerebral proliferative angiopathy (CPA) is a rare vascular disorder that affects normal blood circulation in the brain. Although the structural changes in CPA can be characterized using standard radiologic modalities, assessing the vascular hemodynamics ...

Added value of arterial spin labeling magnetic resonance imaging in pediatric neuroradiology: pitfalls and applications

, 2019
Arterial spin labeling is a noninvasive, non-gadolinium-dependent magnetic resonance imaging (MRI) technique to assess cerebral blood flow. It provides insight into both tissue metabolic activity and vascular supply. Because of its non-sensitivity toward

Pseudo-continuous and territorial arterial spin labeling MRI for assessment of cerebral perfusion in moyamoya disease after revascularization: A comparative study with digital subtraction angiography

Heliyon
Purpose: To evaluate if pseudo-continuous arterial spin labeling (pcASL) and territorial ASL (tASL) can assess cerebral perfusion post-revascularization in Moyamoya disease and compare with digital subtraction angiography (DSA) outcomes.
