Kurtosis fractional anisotropy, its contrast and estimation by proxy [PDF]

Scientific Reports, 2016
AbstractThe diffusion kurtosis observed with diffusion magnetic resonance imaging (dMRI) may vary with direction. This directional variation is summarized in the scalar kurtosis fractional anisotropy (KFA). Recent studies suggest that kurtosis anisotropy offers microstructural contrast not contained in other commonly used dMRI markers.

Genetic analysis of cortical thickness and fractional anisotropy of water diffusion in the brain [PDF]

, 2011
Objectives: The thickness of the brain’s cortical gray matter (GM) and the fractional anisotropy (FA) of the cerebral white matter (WM) each follow an inverted U-shape trajectory with age. The two measures are positively correlated and may be modulated

Myelin water fraction in relation to fractional anisotropy and reading in 10-year-old children [PDF]

Brain Structure and Function, 2021
Abstract Diffusion-weighted imaging studies have repeatedly shown that white matter correlates with reading throughout development. However, the neurobiological interpretation of this relationship is constrained by the limited microstructural specificity of diffusion imaging.

Diffusion tensor imaging and diffusion-weighted imaging on axillary lymph node status in breast cancer patients

Diagnostic and Interventional Radiology, 2022
PURPOSEThis article will examine the usefulness of diffusion tensor imaging (DTI) and diffusion-weighted imaging (DWI) on the assessment of axillary lymph nodes (ALN) of breast cancer patients.METHODSAxillary lymph nodes in 66 breast cancer patients were

Visualization of infarction using fractional anisotropy [PDF]

Journal of Cardiovascular Magnetic Resonance, 2010
Introduction Accurate localization of ischemia is crucial in diagnosis of myocardial disease. The zHARP[1] pulse sequence quantifies myocardial function by computing a three-dimensional strain tensor at each voxel, from which principal strain values and orientations can be computed.

Multi-centre reproducibility of diffusion MRI parameters for clinical sequences in the brain. [PDF]

, 2015
The purpose of this work was to assess the reproducibility of diffusion imaging, and in particular the apparent diffusion coefficient (ADC), intra-voxel incoherent motion (IVIM) parameters and diffusion tensor imaging (DTI) parameters, across multiple ...

Developmental and regional dependence of macromolecular proton fraction and fractional anisotropy in fixed brain tissue. [PDF]

NMR Biomed, 2023
An important advantage of imaging fixed tissue is a gain in signal‐to‐noise ratio and in resolution due to unlimited scan time. However, the fidelity of quantitative MRI parameters in fixed brain tissue, particularly in developmental settings, requires validation.
