© 2018 The Author(s). Magnetic resonance spectroscopic imaging (MRSI) is a promising technique in both experimental and clinical settings. However, to date, MRSI has been hampered by prohibitively long acquisition times and artifacts caused by subje

Feasibility and reproducibility of neurochemical profile quantification in the human hippocampus at 3 T

Autor: Bednařík, P, Moheet, A, Deelchand, DK, Emir, UE, Eberly, LE, Bareš, M, Seaquist, ER, Öz, G

Hippocampal dysfunction is known to be associated with several neurological and neuropsychiatric disorders such as Alzheimer's disease, epilepsy, schizophrenia and depression; therefore, there has been significant clinical interest in studying hippoc

Regional neurochemical profiles in the human brain measured by ¹H MRS at 7 T using local B₁ shimming

Autor: Emir, UE, Auerbach, EJ, Van De Moortele, PF, Marjańska, M, Uğurbil, K, Terpstra, M, Tkáč, I, Oz, G

Increased sensitivity and chemical shift dispersion at ultra-high magnetic fields enable the precise quantification of an extended range of brain metabolites from (1)H MRS. However, all previous neurochemical profiling studies using single-voxel MRS

Noninvasive quantification of ascorbate and glutathione concentration in the elderly human brain

Autor: Emir, UE, Raatz, S, McPherson, S, Hodges, JS, Torkelson, C, Tawfik, P, White, T, Terpstra, M

Publikováno v: NMR in Biomedicine, 24(7), 888-894. John Wiley & Sons Ltd.

In this study, ascorbate (Asc) and glutathione (GSH) concentrations were quantified noninvasively using double-edited (1)H MRS at 4 T in the occipital cortex of healthy young [age (mean +/- standard deviation) = 20.4 +/- 1.4 years] and elderly (age =
