Imaging at high spatial resolution is requisite for
imaging the intracranial vasculature; however, achieving
high spatial resolution is challenging due to competing
factors including SNR, scan time, and artifacts. In
particular, as the resolution increases the need for
flow compensation increases which can lead to lower SNR
and increases sensitivity to higher order motion
effects. In this work, we investigate high spatial
resolution angiography utilizing accelerated Contrast
Enhanced (CE) ultra-short echo (UTE) imaging, and
demonstrate high resolution imaging of the vascular
system with 0.57mm isotropic resolution.
