Arterial Spin Labeling: Techniques, Clinical Applications, and Interpretation.

Radiographics, 2023
Arterial spin labeling (ASL) is an emerging noninvasive MRI technique for assessing cerebral perfusion. An important advantage of ASL perfusion is the lack of a requirement for an exogenous tracer.

Quantitative multiple boli arterial spin labeling

Magnetic Resonance Imaging, 2023
The mbASL sequence is a hybrid between PASL and pCASL. It was shown to produce high SNR perfusion data. Quantification is crucial in order to produce accurate mbASL CBF maps. We have shown successful quantification by modifying the Buxton ASL kinetic model, optimising the number of pulses used for inversion and examining the optimal labelling slab ...

Arterial Transit Time‐Based Multidelay Combination Strategy Improves Arterial Spin Labeling Cerebral Blood Flow Measurement Accuracy in Severe Steno‐Occlusive Diseases

Journal of Magnetic Resonance Imaging, 2021
Although perfusion imaging plays a key role in the management of steno‐occlusive diseases, the clinical usefulness of arterial spin labeling (ASL) is limited by technical issues.

Acceleration‐selective arterial spin labeling

Magnetic Resonance in Medicine, 2013
In this study, a new arterial spin labeling (ASL) method with spatially nonselective labeling is introduced, based on the acceleration of flowing spins, which is able to image brain perfusion with minimal contamination from venous signal. This method is termed acceleration‐selective ASL (AccASL) and resembles velocity‐selective ASL (VSASL), with the ...
