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.
