Voxel Placement Precision for GABA-Edited Magnetic Resonance Spectroscopy
The purpose of the present study was to assess the reproducibility of voxel placement for GABA-edited MRS. GABA-edited MRS data were acquired in 13 healthy volunteers from (3 cm)3 voxel; and within the same session a second acquisition was independently prescribed. A three-dimensional voxel mask image was reconstructed in T1-image-space using the SVMask tool (in house software). Reproducibility...
متن کاملGABA editing at 3T with Macromolecule Suppression: MEGA-SPECIAL
Introduction. One commonly used method for in-vivo magnetic resonance spectroscopy (MRS) detection of γ-aminobutyric acid (GABA) is the MEGA-PRESS technique [1], which enables direct observation of the GABA resonance at 3.02 ppm. Unfortunately, direct quantification of GABA using MEGA-PRESS is complicated by co-editing of macromolecule (MM) signals, which also resonate at 3.02 ppm [2]. Two meth...
متن کاملProton magnetic resonance spectroscopy in focal cortical dysplasia at 3T
PURPOSE Focal cortical dysplasia (FCD) type II is a frequent cause of medically intractable epilepsy. On conventional MRI diagnosis may be difficult. The purpose of our study was to assess the metabolic characteristics of MRI-typical or neuropathologically confirmed FCD II lesions at 3T. METHODS In a prospective study, 13 patients with drug-resistant epilepsy and MRI diagnosis of FCD II (seve...
متن کاملEdited magnetic resonance spectroscopy detects an age-related decline in brain GABA levels
Gamma-aminobutyric acid (GABA) is the primary inhibitory neurotransmitter in the brain. Although measurements of GABA levels in vivo in the human brain using edited proton magnetic resonance spectroscopy ((1)H-MRS) have been established for some time, it is has not been established how regional GABA levels vary with age in the normal human brain. In this study, 49 healthy men and 51 healthy wom...
