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.

Selective Arterial Spin Labeling

Topics in Magnetic Resonance Imagin, 2016
Knowledge of the distribution of blood flowing from the heart to the brain-feeding arteries is important for the understanding and diagnosis of cerebrovascular diseases. Due to anatomical variations and anomalies within the cerebrovasculature, together with changes caused by various cerebrovascular diseases, there is high variability in the ...
