The superior labeling band of FAIR can also label blood, which results in adverse venous artifacts and an inconsistency between the single subtraction blood flow quantification model and the experimental data. To overcome the difficulties faced by the traditional FAIR-based PASL technique, an asymmetric FAIR - FAIR with Active Suppression of Superior Tagging (FAIR ASST) - was proposed and evaluated. Among various possible ways for the suppression of FAIRs superior tagging, the method using one pre-inversion and two post-inversion superior saturations was found to be effective and efficient.
