A Beginner's Guide to Arterial Spin Labeling (ASL) Image Processing
Frontiers in Radiology, 2022 Arterial spin labeling (ASL) is a non-invasive and cost-effective MRI technique for brain perfusion measurements. While it has developed into a robust technique for scientific and clinical use, its image processing can still be daunting.

ASL-BIDS, the brain imaging data structure extension for arterial spin labeling
Scientific Data, 2022 Arterial spin labeling (ASL) is a non-invasive MRI technique that allows for quantitative measurement of cerebral perfusion. Incomplete or inaccurate reporting of acquisition parameters complicates quantification, analysis, and sharing of ASL data ...

Optimization of pseudo-continuous arterial spin labeling for brain perfusion imaging in the intraoperative setting. [PDF]
Magn Reson MedAbstract Purpose Pseudo‐continuous arterial spin labeling (PCASL) efficiency during intraoperative MRI is degraded due to large field inhomogeneities observed in some patients and lower arterial blood velocities induced by anesthesia. The purpose of this work was to maximize labeling efficiency during intraoperative MRI by optimizing PCASL parameters ...
