In this article, we provide a brief summary of the ASL tech-nique, discuss potential pitfalls and artifacts, review current and commonly used clinical applications, and provide a prac-tical approach for …

ASL suffers from the same artifacts as other MR techniques, including susceptibility, flow, and motion. However, some of these problems manifest differently on ASL than on conventional images.

Sep 1, 2025 · Arterial spin labelling (ASL) is a magnetic resonance (MR) perfusion technique used in neuroradiology. Images obtained with ASL are reconstructed and represented as cerebral blood flow …

Sep 12, 2025 · The main idea in ASL is to obtain a labeled image or tagged image and a control image, in which the static tissue signals are identical but the magnetization of the inflowing blood is different.

Mar 6, 2014 · Arterial spin labeling (ASL) is an MRI method that enables the measurement of tissue perfusion without the use of exogenous contrast agents by magnetically tagging the water in …

Knowledge of pathophysiologic changes in blood flow and common artifacts inherent to the sequence allows accurate interpretation of ASL when performed as part of a routine clinical imaging protocol.

Nov 30, 2013 · ASL is a noninvasive MR perfusion method, which measures blood perfusion using magnetically labeled arterial blood water as endogenous tracer and can provide repeated and …

The authors review the technical and physiologic basis of ASL perfusion, as well as artifacts, pitfalls, and its current clinical applications. A practical approach for interpreting ASL findings is also suggested.

Jun 14, 2022 · Starting with an introduction of the physiology and MRI technique behind ASL, and how they interact with the image processing, we present an overview of processing pipelines and explain …

Nov 11, 2022 · In this article, we provide a brief summary of the ASL technique, discuss potential pitfalls and artifacts, review current and commonly used clinical applications, and provide a practical …
