1 In vivo brain spectra acquired on a healthy volunteer by using a CT-PRESS sequence at 7T.
In vivo brain spectra acquired on a healthy volunteer by using a CT-PRESS sequence at 7T. Spectrum is courtesy of Drs Dirk Mayer and Daniel Spielman, Stanford University, Stanford, California. Plotted below the in vivo data are simulated spectra of individual metabolites, as generated by the CT-PRESS acquisitions.103 Metabolites shown are: phosphocreatine (PCr), creatine (Cr), myo-inositol (mI), scyllo-inositol (sI), N-acetylaspartate (NAA), N-acetyl aspartylglutamate (NAAG), alanine (Ala), aspartate (Asp), glutamate (Glu), glutamine (Gln), Choline (Cho), gamma-aminobutyric acid (GABA), glutathione (GSH), phosphoethanolamine (PE), glucose (Glc), taurine (Tau). Scanner: 7T whole-body scanner (MR950; GE Healthcare, Milwaukee, Wisconsin). RF coil: Nova head coil. Scan parameters: resolution = 2 × 2 × 2 cm3; voxel centrally located in the supertentorial brain, scanning time = 5 minutes. P. Balchandani, and T.P.
