Slice-specific spokes pulses were designed and applied
for high resolution GRE imaging at 9.4T. The problems of
SNR drop out and contrast variations due to RF
inhomogeneity which is typical at ultra high field were
mitigated by the spokes pulses. This led to improvements
in both SNR and contrast, which ultimately allows fine
vein structures in cortex to be observed in these high
resolution images.
