As part of the Open Science Initiative for Perfusion Imaging (OSIPI), the aim of this work is to develop a Lexicon and Reporting Recommendations for arterial spin labeling (ASL) perfusion MR imaging and analysis. The lexicon describes standardized nomenclature and terminology for ASL acquisition techniques, parameters and physiological constants that are required for quantitative analysis. Additionally, a community-endorsed recommendation for reporting acquisition parameters in publications is provided. Overall, this project aims to improve the clarity and consistency of ASL terminology, which in turn will facilitate comparisons between different studies.
