In this study the variation in the measured apparent T₂ was assessed over different slices for venous velocity selective inversion (vVSI) with 2D EPI readout in the sagittal sinus and we compared vVSI with 2D EPI and 3D multi-echo spin echo EPI (mTE-SE-EPI) readout to the gold standard TRUST. With the 2D EPI readout the T₂ increases significantly over the slices.
