Task force 4.1: ASL Lexicon
The guidelines developed by TF 4.1 will enable interoperability and facilitate the comparison of results produced by different ASL analysis tools, studies or sites. We aim to harmonize and increase the detail in the description of parameters and configurations, enable encoding of the complete perfusion imaging workflow, and pave the way for consensus building. An important application will be the amendment of the DICOM standard for ASL perfusion parametric maps, as well as BIDS extensions, and development of demonstrations and use cases.

Ongoing projects
In the roadmap 2023-2025, TF4.1 is going to transfer the current Lexicon to a user-friendly webpage on the OSIPI website, to complement and expand on the MRM paper. Also, the Lexicon will be expanded to cover more ASL methods. Additionally, we will verify harmonization of the Lexicon with ASL-BIDS, and highlight and explain discrepancies where they are unavoidable. Finally, in collaboration with OSIPI TF 5.2, we are going to develop some practical introductory multi-media educational tools, using terminology from the Lexicon, for clinicians and radiographers/technicians, to try to break down barriers to the use of ASL in the clinical domain.
