We here report our recent phantom results using wavelet encoding (WE) combined with parallel imaging (PI, WE-PI) to acquire 1D magnetic resonance spectroscopic imaging (MRSI). Two sets of experiments are performed with the same acceleration factor (R = 2) and two different resolutions (N = 4 and N = 8). The results confirm that WE-PI reduces further the acquisition time by approximately the acceleration factor R, and preserves the spatial metabolite distribution with minimal loss of the signal-to-noise ratio (SNR) as compared to the WE-SI technique.
