Multivendor implementation and comparison of volumetric whole‐brain echo‐planar MR spectroscopic imaging

To assess volumetric proton MR spectroscopic imaging (MRSI) of the human brain on multivendor MRI instruments.Echo-planar spectroscopic imaging was developed on instruments from three manufacturers, with matched specifications and acquisition protocols that accounted for differences in sampling performance, radiofrequency (RF) power, and data formats. Intersite reproducibility was evaluated for signal-normalized maps of N-acetylaspartate (NAA),...
