We have recently developed a new approach to partial volume estimation that uses surface segmentations (for example, those produced by FreeSurfer). We compare this approach to conventional volumetric PV estimation for the application of PV correction to two ASL datasets and find evidence in support of using surface-derived PV estimates.
