Deformation and resolution issues in partial volume correction of 2D arterial spin labeling data

Petr, J.; Mutsaerts, H. J.; de Vita, E.; Maus, J.; van den Hoff, J.; Asllani, I.

Partial volume (PV) effects are a well-recognized confounder in arterial spin labeling due to its limited spatial resolution. Several algorithms exist to correct for these errors. Nevertheless, PVcorrection is rarely used, mainly because the PV maps obtained from segmented T1-weighted images are regarded as not being suficiently reliable when transformed into ASL space. Here, we show the impact of spatial deformation and resolution in the PV-maps used for PV-correction in the calculation of mean total gray matter (GM) cerebral blood flow (CBF). We also show how the deformations affect the calculation of PV-uncorrected mean GM CBF.
