Rosette Spectroscopic Imaging for Whole‐Brain Slab Metabolite Mapping at 7T: Acceleration Potential and Reproducibility

Human Brain Mapping, Volume 46, Issue 4, March 2025.
2D‐/3D‐ whole‐brain slab non‐lipid‐suppression ultra‐short‐TE 1H‐MRSI acquisition schemes were developed using the rosette trajectory at 7T. This method showed excellent intra‐session reproducibility, with the coefficients of variance of major metabolites, like glutamate, below 5%.
