1 lip 2007 · Diffusion tensor imaging (DTI) is a promising method for characterizing microstructural changes or differences with neuropathology and treatment. The diffusion tensor may be used to characterize the magnitude, the degree of anisotropy, and the orientation of directional diffusion.
16 wrz 2021 · Flow of cerebral ISF (Q ISF) and CSF (Q CSF) is depicted in green, while the cerebral vascular circulation is depicted in red. The intracranial compartments are represented by the capacitors C BR (orange), C VEN (green), and C SAS (purple) for brain, ventricles, and subarachnoid space, respectively.
DWI is sensitive to the direction and strength of molecular diffusion (primarily water) in the brain. It reveals characteristics of the brain macro-structure and micro-structure. (e.g., Tournier et al., 2011, Magn Reson Med). It allows inferences about structural connectivity (e.g., Fillard et al., 2011, Neuroimage). Macro-structure.
12 lis 2013 · Although the best known use of diffusion-weighted imaging (DWI) in MRI of the brain is detection of acute vaso-occlusive infarct, diffusion abnormalities occur in a wide spectrum of neurological pathologies.
2 gru 2014 · Regulation of the composition and volume of these fluids is important for effective functioning of brain cells and is achieved by barriers that prevent free exchange between CNS and blood and by mechanisms that secrete fluid of controlled composition into the brain and distribute and reabsorb it.
15 sie 2012 · First, diffusion MRI has been used to obtain images of brain function, based on the idea that diffusion MRI could also be made sensitive to blood flow, through the intravoxel incoherent motion (IVIM) concept.
4 cze 2018 · This review discusses ex vivo diffusion magnetic resonance imaging (dMRI) as an important research tool for neuroanatomical investigations and the validation of in vivo dMRI techniques, with a focus on the human brain.
