OSIPI Task Force 4.1: ASL lexicon

Task force aims

Develop guidelines for reporting of ASL image acquisition and analysis

Task force description

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.
