In vivo MRSI at 7T offers advantages compared to lower field strengths, in particular higher SNR and improved spectral resolution. However, spectral quality is often limited by strong B1+ inhomogeneities, motion-related artifacts and scanner instability related B0 field drifts. To overcome these limitations, we have developed a 1D-semiLASER 2D-spiral-encoded MRSI sequence with real-time motion monitoring/correction using 3D EPI-based navigators (vNavs). Besides sequence stability we show that accurate B1-insensitive excitation can be achieved throughout the slice until the border of the brain. Using 7T-optimized motion correction, high spectral and metabolic map qualities are feasible even in the presence of motion.
