Benefits and challenges of multi-delay arterial spin labeling in clinical practice: measuring perfusion and cerebrovascular reactivity in intracranial steno-occlusive disease

Insights into Imaging
Magnetic resonance imaging (MRI) techniques have now widely replaced positron emission tomography (PET) as the modality of choice to assess cerebrovascular reactivity (CVR) and other hemodynamic parameters in intracranial steno-occlusive disease (ISOD ...

Comparison of velocity- and acceleration-selective arterial spin labeling with [O]HO positron emission tomography

, 2015
In the last decade spatially nonselective arterial spin labeling (SNS-ASL) methods such as velocity-selective ASL (VS-ASL) and acceleration-selective ASL have been introduced, which label spins based on their flow velocity or acceleration rather than ...
