Fast imaging sequences are commonly used for proton
imaging because of their high acquisition efficiency. In
this work three spiral imaging sequences which used
either RF spoiling, gradient spoiling or balanced
gradients were adapted for sodium imaging at 9.4 T and
compared to one another based on achieved image quality
and SNR. Balanced steady-state free precession imaging
provided the highest SNR while producing only negligible
image artefacts. Due to the efficient acquisition with a
sensitive 27-channel receiver array images with a
nominal spatial resolution of 1.5x1.5x4.0 mm
3
and
an acceptable SNR could be acquired in 10 min.
