Readout schemes for multi-slice pulsed ASL of the human
kidney at 3T are evaluated. Gradient echo (GE) based
schemes of balanced fast field echo (bFFE) and gradient
echo echo-planar imaging (GE-EPI) and spin echo (SE)
based schemes of spin echo EPI (SE-EPI) and turbo spin
echo (TSE) are compared for temporal SNR (tSNR), image
SNR, spatial coverage, perfusion quantification and
variability across slices and subjects. Gradient echo
based schemes (bFFE and GE-EPI) provide optimal PWI-SNR
and tSNR, with GE-EPI yielding multi-slice coverage in a
short acquisition time.
