We show high-resolution 3D EPI acquisitions at 9.4T,
using kT-points excitation for B1+ homogenisation.
Remarkable image quality at 0.75mm isotropic resolution
is achieved across the whole-brain, whereas images
acquired in CP mode suffer considerably loss of signal
and contrast especially in central regions. The images
shown hold promise for application to high-resolution
BOLD fMRI, as well as fast structural imaging including
applications such as rapid quantitative susceptibility
mapping (QSM).
