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.
