Understanding the Physiopathology Behind Axial and Radial Diffusivity Changes—What Do We Know?
The use of the diffusion tensor imaging (DTI) is rapidly growing in the neuroimaging field. Nevertheless, rigorously performed quantitative validation of DTI pathologic metrics remains very limited owing to the difficulty in co-registering quantitative histology findings with magnetic resonance imaging. The aim of this review is to summarize the existing state-of-the-art knowledge with respect ...
متن کاملAxial and Radial Diffusivity Measures Detect Brain Tissue Injury in Heart Failure Patients
Heart failure (HF) patients show brain tissue loss or injury in autonomic, cognitive, and emotional regulatory areas (1, 2); the regions with tissue injury overlap sites of altered functional MRI signals to autonomic challenges (3, 4). Some structural injury appears on T2-relaxometry procedures, and could result from different pathological processes, including hypoxia/ischemia accompanying perf...
متن کاملGlobal and regional brain mean diffusivity changes in patients with heart failure.
Heart failure (HF) patients show gray and white matter changes in multiple brain sites, including autonomic and motor coordination areas. It is unclear whether the changes represent acute or chronic tissue pathology, a distinction necessary for understanding pathological processes that can be resolved with diffusion tensor imaging (DTI)-based mean diffusivity (MD) procedures. We collected four ...
متن کاملAxial and Radial Oxylipin Transport.
Jasmonates are oxygenated lipids (oxylipins) that control defense gene expression in response to cell damage in plants. How mobile are these potent mediators within tissues? Exploiting a series of 13-lipoxygenase (13-lox) mutants in Arabidopsis (Arabidopsis thaliana) that displays impaired jasmonic acid (JA) synthesis in specific cell types and using JA-inducible reporters, we mapped the extent...
متن کاملAbout "axial" and "radial" diffusivities.
This article presents the potential problems arising from the use of "axial" and "radial" diffusivities, derived from the eigenvalues of the diffusion tensor, and their interpretation in terms of the underlying biophysical properties, such as myelin and axonal density. Simulated and in vivo data are shown. The simulations demonstrate that a change in "radial" diffusivity can cause a fictitious ...
