7T MRSI (HFMRC, MU Vienna) Example Data: Raw MM Spectra
Creators
Description
Data from the Vienna 7T MRSI group
Contact: wolfgang.bogner@meduniwien.ac.at , mpovaza1@jhmi.edu
Format: JMRUI text file
Field strength: 7T
Scanner type: Siemens 7T Magnetom
Sequence type: Double Inversion Recovery single-slice FID-MRSI, cartesian phase encoding
Technique: Metabolite Nulling Using Double Inversion Recovery
Spectrum Type: Metabolite-Nulled Macromolecular spectrum
Pre-processing: Spectra summed across chosen ROI / Metabolite Residuals Removed using AMARES
Subjects: Healthy young (25-35y) volunteers
Acquisition date: 2014-2015
Details on the acquisition and pre-processing of these datasets can be found in 1. (Považan et al., NI, 2015). In case of further questions, please contact authors.
Notes
The modulation of the baseline is due to the difference between the acquisition delay of the sequence (TE*=1.3ms) and the display (TE*=0ms)
