Shown are the T1-weighted postcontrast MRI, total N-acetylaspartate (tNAA), total choline (tCho), total creatine (tCr), glutamate (Glu), glutamine (Gln), myo-inositol (mIns) and sum of lipids (Lip). The single-slice FID-MRSI was acquired in 6 min with 6-fold accelerated phase-encoding, voxel size of 3.4 x 3.4 x 8 mm3 and TR/AD of 600/1.3 ms. From Trattnig et al46
