We
present our first in vivo results demonstrating wavelet encoded 3D
spectroscopic imaging (WE-SI) at high magnetic field (3T) compared with
standard, Fourier-encoded, chemical shift imaging (CSI). As previously demonstrated with phantom
results, we confirm a reduction in acquisition time and pixel bleed for
equivalent number of encodes as compared to CSI, with the predicted drop in
SNR. In-vivo results show that WE-SI preserves metabolite signal
distributions while reducing acquisition time, demonstrating that WE-SI is
providing accurate MRSI results with higher sensitivity at higher fields.
