Proton T1 relaxation times of metabolites in human occipital white matter and grey matter at 7T
Introduction Knowledge of longitudinal relaxation times of metabolites is essential for optimization of measurement parameters, for the quantification of metabolites in single voxel MR spectroscopy and spectroscopic imaging and for investigating cell microenvironment changes induced by physiological and pathological processes. Previous studies have reported T1 values for N-acetylaspartate (NAA)...
متن کاملBrain Structural Correlates of INTELLIGENCE in ADHD Individuals
Neuroimaging evidences have shown the association of intelligence with several structural brain properties in normal individuals. However, this association for attention deficit hyperactivity disorder (ADHD) is need to be investigated. we estimated grey matter density of the brain using MRI scanning on 56 ADHD individuals comprising 30 combined (age=10.44±2.41, IQ=112.13±13.15, male, 24 right h...
متن کاملPathological Assessment of Brain White Matter in Relapsing-Remitting MS Patients using Quantitative Magnetization Transfer Imaging
Introduction: Multiple sclerosis (MS) is characterized by lesions in the white matter (WM) of the central nervous system. Magnetic resonance imaging is the most specific and sensitive method for diagnosis of multiple sclerosis. However, the ability of conventional MRI to show histopathologic heterogeneity of MS lesions is insufficient. Quantitative magnetization transfer imaging (qMTI) is a rel...
متن کاملIs the macromolecule signal tissue-specific in healthy human brain? A (1)H MRS study at 7 Tesla in the occipital lobe.
PURPOSE The macromolecule signal plays a key role in the precision and the accuracy of the metabolite quantification in short-TE (1) H MR spectroscopy. Macromolecules have been reported at 1.5 Tesla (T) to depend on the cerebral studied region and to be age specific. As metabolite concentrations vary locally, information about the profile of the macromolecule signal in different tissues may be ...
