  • Brain Volume Changes in Aging Individuals With Normal Cognition
    In particular, the cortical gray matter showed a consistent pattern of volume loss in each brain lobe with aging The white matter showed an age-related decrease in volume and an accelerated atrophy rate (regression coefficient, −0 016 [95% CI, −0 012 to –0 011]; P < 001)
  • Age-Related Total Gray Matter and White Matter Changes in Normal Adult . . .
    We investigated the effects of age and sex on total fractional GM (%GM) and total fractional WM (%WM) volumes by using volumetric MR imaging in healthy adults METHODS: Fifty-four healthy volunteers (22 men, 32 women) aged 20–86 years underwent dual-echo fast spin-echo MR imaging
  • The NeuroQuant Normative Database - Cortechs. ai
    Volumes of individually segmented structures (reported as the percentage of intracranial volume (ICV)), in addition to the patient’s age and gender information, were entered into a MATLAB curve fitting and percentile generation program developed by CorTechs Labs
  • Gray Matter Volume and Cognitive Performance During Normal . . . - Frontiers
    In the present study, we evaluated the effect of age (older group, OG relative to middle-aged group, MAG) on GM volume, using a whole brain voxel-related GM analysis, in conjunction with a cognitive-score evaluation
  • Correlations among Brain Gray Matter Volumes, Age, Gender, and . . . - PLOS
    Analysis of global gray matter volume revealed a significant negative correlation between gray matter ratio (gray matter volume divided by intracranial volume) and age in both genders, and a significant interaction effect of age × gender on the gray matter ratio
  • Cross-Sectional Volumes and Trajectories of the Human Brain, Gray . . .
    This scoping meta-analysis aggregates normative reference values for BV and three related volumetrics—gray matter volume (GMV), white matter volume (WMV) and cerebrospinal fluid volume (CSFV)—from typically-aging adults studied cross-sectionally using magnetic resonance imaging (MRI)
  • Brain size and grey matter volume in the healthy human brain
    Magnetic resonance imaging was used to evaluate the in£uence of sex and brain size on compartmental brain volumes (grey matter, white matter, CSF) in a large and well-matched sample of neurologically normal women (n1⁄450) and men (n1⁄450)
  • Prefrontal Gray and White Matter Volumes in Healthy Aging and Alzheimer . . .
    Using quantitative MRI, we examined gray and white matter volume differences in young healthy elderly (YHE) (mean age, 70 years), old healthy elderly (OHE) (mean age, 90 years), and a group of subjects with AD (mean age, 70 years) age matched to YHE
  • Imaging the aging brain: study design and baseline findings of the . . .
    For MRI analysis, distributions of mean total gray matter, white matter, and CSF volume in percentage of total intracranial volume of the cohort were 47 81% (SD 2 04), 35 59% (SD 2 76), and 16 61% (SD 3 12) TIV was significantly different in gender (t (140) = 6 41; p = 2 07×10 −9), with females demonstrating smaller brain volumes
  • One-year Age Changes in MRI Brain Volumes in Older Adults
    Age differences in the gray matter distributions are shown at bottom as the difference between the average maps for age 59–69 (64 6 ± 3 2) and age 70–85 years (77 3 ± 4 7) Greater gray matter volumes in younger compared with older subjects are apparent in the hippocampus (H), inferior (IT) and mesial temporal lobes, orbital frontal
