Dataset Open Access

7T MRSI (HFMRC, MU Vienna) Example Data: Raw MM Spectra

Povazan, Michal; Bogner, Wolfgang

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.

 

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)
