Most sodium MR studies are performed using 3D
ultra-short echo time (UTE) sequences with isotropic
resolution. For some applications, however, anisotropic
resolution is preferred to reduce partial-volume effects
that hamper sodium quantification. No analytical formula
could be found for the azimuth angle to acquire k-space
uniformly on an ellipsoidal surface using the golden
ratio (GR). In this work, a 3D acquisition scheme is
presented to achieve high SNR efficiency for UTE imaging
with anisotropic resolution and retrospective gating
using the GR. This SNR gain can be invested in higher
resolutions and/or measurement time, which is important
for sodium MRI.
