Partial Volume effects (PVE) in ASL have been shown to lead to significant quantification errors. PVE in ASL fingerprinting data have not been previously investigated but are also likely to introduce significant errors in quantification, given their typically coarse resolution. A simple algorithm is presented to calculate tissue fraction maps from ASL MRF timeseries data without collection of additional anatomical images. These fraction maps can be used to implement partial volume corrections as well as identify tissue abnormalities.
