Magnetic resonance spectroscopic imaging (MRSI) at ultra-high field strengths is a promising technique for mapping of the metabolites over the entire brain volume with a high signal to noise ratio. However, long acquisition time is a major limitation in MRSI. Along with short repetition times (TR) [4] parallel imaging strategies can help accelerate the scan by acquiring only a fraction of the data points in k-space, but an appropriate unfolding reconstruction algorithm is required. To that end, a target driven SENSE [3] reconstruction algorithm has been introduced [1], which minimizes the effects of voxel bleeding. This study represents the first demonstration of short TR twofold SENSE accelerated multi-slice FID MRSI of the human brain at 9.4T.
