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.
