Sodium ion apparent diffusion coefficient in living rat brain.
The apparent diffusion coefficient (ADC) of Na(+) was determined in live rat brain. The brain extracellular-to-intracellular Na(+) content ratio is approximately 8:2, which is the inverse of that for water in these spaces. Consequently, the ADC of Na(+) is primarily affected by motion in the extracellular space, and Na(+) can be viewed as a reporter molecule for motion in that space. Likewise, ...
متن کاملBiexponential apparent diffusion coefficient parametrization in adult vs newborn brain.
The decay of brain water signal with b-factor in adult and newborn brains has been measured over an extended b-factor range. Measurements of the apparent diffusion coefficient (ADC) decay curves were made at 16 b-factors from 100 to 5000 s/mm(2) along three orthogonal directions using a line scan diffusion imaging (LSDI) sequence to acquire data from 0.09 ml voxels in a mid-brain axial slice. R...
متن کاملGlobal and region-specific analyses of apparent diffusion coefficient in dentatorubral-pallidoluysian atrophy.
BACKGROUND AND PURPOSE Dentatorubral-pallidoluysian atrophy (DRPLA) is an autosomal dominant spinocerebellar ataxia. Techniques for the quantitative assessment of neurodegenerative lesions remain to be established in this disease. We attempted to quantify global and region-specific neurodegeneration in DRPLA using analysis of apparent diffusion coefficient (ADC) maps. METHODS Diffusion-weight...
متن کاملOptimised diffusion-weighting for measurement of apparent diffusion coefficient (ADC) in human brain.
This work studies the effect of diffusion-weighting on the precision of measurements of the apparent diffusion coefficient (ADC, or D) by diffusion-weighted magnetic resonance imaging. The precision in the value of the ADC was described in terms of a diffusion-to-noise ratio (DNR) which was calculated as the signal-to-noise ratio in the resultant ADC. A theoretical analysis decomposed the DNR i...
متن کاملWhole-brain apparent diffusion coefficient in traumatic brain injury: correlation with Glasgow Coma Scale score.
BACKGROUND AND PURPOSE Patients with traumatic brain injury (TBI) and low Glasgow coma scale (GCS) scores may have severe injury associated with cellular disruption that can be studied with whole-brain apparent diffusion coefficient (ADC) histograms. We retrospectively studied this hypothesis and correlated ADC with GCS. METHODS Twenty-one patients (37.81 +/- 41.3 years) with TBI were enrolle...
