Spectroscopic imaging (SI) on the mouse brain is an attractive tool to quantitatively determine brain metabolite concentrations on different models of human diseases. However, SI suffers from low signal-to-noise ratio and long acquisition times, which restrain the practically achievable spatial resolution. In this work, a novel receive-only cryogenic phased array coil was used to overcome those issues. Using this setup, we could acquire spectra of excellent quality on a mouse model of glioblastoma at resolutions of 0.32 μl per voxel in less than 2h.
