Diffusion‐weighted single voxel experiments conducted at b‐values up to 1 × 104 smm−2 yielded biexponential signal attenuation curves for both normal and ischemic brain. The relative fractions of the rapidly and slowly decaying components (f1, f2)are f1 = 0.80 ± 0.02, f2 = 0.17 ± 0.02 in healthy adult rat brain and f1 = 0.90 ± 0.02, f2 = 0.11 ± 0.01 in normal neonatal rat brain, whereas the corresponding values for the postmortem situation are f1 = 0.69 ± 0.02, f2 = 0.33 ± 0.02. It is… Expand
The existence of biexponential signal decay in magnetic resonance diffusion‐weighted imaging appears to be independent of compartmentalization
TLDR
The results suggest that compartmentalization is not an essential feature of biexponential decay in diffusion experiments, and thus diffusion‐weighted imaging in brain pathologies may not need to include water compartments. Expand
Diffusion in compartmental systems. II. Diffusion‐weighted measurements of rat brain tissue in vivo and postmortem at very large b‐values
TLDR
The behavior of the slowest decaying component can be fully understood in terms of a long time limit of a modified Kärger formalism for a two‐compartment system. Expand

TLDR
The experimental results are consistent with the theoretical predictions used to estimate the exchange time of diffusing water molecules for a model of human brain tissue, and show diffusion time dependence for the slow diffusion coefficient which has not been reported. Expand
Separating changes in the intra‐ and extracellular water apparent diffusion coefficient following focal cerebral ischemia in the rat brain
TLDR
It is suggested that the IC water ADC determines the overall water ADC value in normal and ischemic rat brain. Expand
Water diffusion compartmentation at high b values in ischemic human brain.
TLDR
The restricted diffusion observed in the early stroke is mainly related to a redistribution of water from the FDC to the SDC, and the respective contributions to the signal intensity of SDC and FDC. Expand
Multi‐component apparent diffusion coefficients in human brain: Relationship to spin‐lattice relaxation
In vivo measurements of the human brain tissue water signal decay with b‐factor over an extended b‐factor range up to 6,000 s/mm 2 reveal a nonmonoexponential decay behavior for both gray and whiteExpand
Biexponential apparent diffusion coefficient parametrization in adult vs newborn brain.
TLDR
The results demonstrate that post-natal brain development has a profound affect on the biexponential parameters which characterize the decay of water signal over an extended b-factor range in both gray and white matter. Expand
Water diffusion in rat brain in vivo as detected at very largeb values is multicompartmental
TLDR
It is suggested that the measured ADC at smallb values reflects mainly properties of the restricting boundaries, i.e. the relative volume fractions and the extracellular tortuosity, while the intrinsic intracellular diffusion constant and the exchange time are predicted to have minor influence.

Water diffusion measurements in perfused human hippocampal slices undergoing tonicity changes
TLDR
Water diffusion in 20 perfused human hippocampal slices agreed with previous diffusion studies of rat brain slices and human brain in vivo, and should aid the development of working models of water diffusion in nervous tissue, and thus increase the clinical utility of diffusion MRI. Expand
Multi‐component apparent diffusion coefficients in human brain †
TLDR
The signal decay with increasing b‐factor at fixed echo time from brain tissue in vivo has been measured using a line scan Stejskal–Tanner spin echo diffusion approach in eight healthy adult volunteers, offering a greater parametrization of the water diffusion process for tissue characterization.

Comparisons of changes observed in diffusion‐weighted MR images with changes in the cellular volume measured by electrical impedance in a model of N‐methyl‐D‐aspartate‐induced brain injury in perinatal rats indicate that changes in tissue water diffusion are related to changes in cell volume.

Diffusion‐weighted hyperintensity in ischemic tissues may be temperature‐related, due to rapid accumulation of diffusion‐restricted water in the intracellular space (cytotoxic edema) resulting from the breakdown of the transmembrane pump and/or to microscopic brain pulsations. Expand
