1. Multi-TE preprocessed macromolecule proton MR spectra acquired at 3 T

[Via Github] [Via Open Science Framework]

Formats: INSPECTOR .mat, jMRUI .txt

This dataset comprises metabolite-nulled macromolecule spectra acquired from 10 healthy young adult volunteers scanned at 3 T using a double-inversion-recovery semi-LASER sequence with 8 echo times (20 - 62 ms) from two brain regions (prefrontal and occipital). Voxel-specific segmented brain values are included in the associated Excel spreadsheet. More details about the acquisition can be found in the reference below.

2. Human Metabolomics Database (in vitro NMR) 

3. MRSpec

MRSpec offers a tool to query an open-access database of processed metabolic data from the basal ganglia and parietal-occipital white matter of children, as detailed in Filip Miscevic, Justin Foong, Benjamin Schmitt, Susan Blaser, Michael Brudno, Andreas Schulze.
