TLDR
The principles of ASL perfusion, the types of labeling and the ways to obtain the mapping are presented, and the quality criteria for the mapping obtained are specified, while emphasizing the artifacts.Abstract:
Arterial spin labeling (ASL) perfusion is a MRI technique to quantify tissue blood flow. ASL is a non-invasive technique that labels the protons in the arterial blood by radiofrequency pulses, without the exogenous injection of contrast media. This article has three goals: 1) present the principles of ASL perfusion, the types of labeling and the ways to obtain the mapping; 2) specify and the quality criteria for the mapping obtained, while emphasizing the artifacts; and 3) describe the main encephalic and renal applications.read more

Quantitative imaging of perfusion using a single subtraction (QUIPSS and QUIPSS II)
TL;DR: Two modifications of pulsed ASL (QUIPSS and QUIPSS II) are introduced that avoid this problem by applying additional saturation pulses to control the time duration of the tagged bolus, rendering the technique relatively insensitive to transit delays and improving the quantitation of perfusion.
