Higher order positive semidefinite diffusion tensor imaging [PDF]
, 2010 Due to the well-known limitations of diffusion tensor imaging, high angular resolution diffusion imaging (HARDI) is used to characterize non-Gaussian diffusion processes. One approach to analyzing HARDI data is to model the apparent diffusion coefficient

The physical and biological basis of quantitative parameters derived from diffusion MRI [PDF]
, 2012 Diffusion magnetic resonance imaging is a quantitative imaging technique that measures the underlying molecular diffusion of protons. Diffusion-weighted imaging (DWI) quantifies the apparent diffusion coefficient (ADC) which was first used to detect ...

Diffusion tensor model links to neurite orientation dispersion and density imaging at high b-value in cerebral cortical gray matter [PDF]
, 2019 Diffusion tensor imaging (DTI) and neurite orientation dispersion and density imaging (NODDI) are widely used models to infer microstructural features in the brain from diffusion-weighted MRI. Several studies have recently applied both models to increase

Diffusion tensor imaging and beyond [PDF]
Magnetic Resonance in Medicine, 2011 The diffusion of water molecules inside organic tissues is often anisotropic (1). Namely, if there are aligned structures in the tissue, the apparent diffusion coefficient (ADC) of water may vary depending on the orientation along which the diffusion-weighted (DW) measurements are taken.
