Structural disconnection of the posterior medial frontal cortex reduces speech error monitoring

NeuroImage: Clinical, 2022
Optimal performance in any task relies on the ability to detect and correct errors. The anterior cingulate cortex and the broader posterior medial frontal cortex (pMFC) are active during error processing. However, it is unclear whether damage to the pMFC

Multi-tissue spherical deconvolution of tensor-valued diffusion MRI

NeuroImage, 2021
Multi-tissue constrained spherical deconvolution (MT-CSD) leverages the characteristic b-value dependency of each tissue type to estimate both the apparent tissue densities and the white matter fiber orientation distribution function from diffusion MRI ...

The Olfactory System Revealed: Non-Invasive Mapping by using Constrained Spherical Deconvolution Tractography in Healthy Humans. [PDF]

Front Neuroanat, 2017
Although the olfactory sense has always been considered with less interest than the visual, auditive or somatic senses, it does plays a major role in our ordinary life, with important implication in dangerous situations or in social and emotional ...

How does B-value affect HARDI reconstruction using clinical diffusion MRI data? [PDF]

PLoS ONE, 2015
A number of imaging factors can affect the orientation distribution function (ODF) reconstruction in high angular resolution diffusion imaging (HARDI). The aim of this study was to investigate the effect of the b-value on the HARDI reconstruction and to ...

Diffuse excessive high signal intensity in the preterm brain on advanced MRI represents widespread neuropathology

NeuroImage, 2022
Preterm brains commonly exhibit elevated signal intensity in the white matter on T2-weighted MRI at term-equivalent age. This signal, known as diffuse excessive high signal intensity (DEHSI) or diffuse white matter abnormality (DWMA) when quantitatively ...

Fiber orientation estimation by constrained spherical deconvolution of the anisotropic edge illumination X-ray dark field signal

, 2022
: Determining fiber orientations in a fiber reinforced material with X-ray CT is challenging because the width of the individual fibers is often much smaller than the spatial resolution of the X-ray images.

Enabling constrained spherical deconvolution and diffusional variance decomposition with tensor-valued diffusion MRI [PDF]

, 2021
Abstract Diffusion tensor imaging (DTI) is widely used to extract valuable tissue measurements and white matter (WM) fiber orientations, even though its lack of specificity is now well-known, especially for WM fiber crossings.

Generalized Richardson-Lucy (GRL) for analyzing multi-shell diffusion MRI data

NeuroImage, 2020
Spherical deconvolution is a widely used approach to quantify the fiber orientation distribution (FOD) from diffusion MRI data of the brain. The damped Richardson-Lucy (dRL) is an algorithm developed to perform robust spherical deconvolution on single ...
