NODDI-DTI: Estimating Neurite Orientation and Dispersion Parameters from a Diffusion Tensor in Healthy White Matter

Frontiers in Neuroscience, 2017
The NODDI-DTI signal model is a modification of the NODDI signal model that formally allows interpretation of standard single-shell DTI data in terms of biophysical parameters in healthy human white matter (WM). The NODDI-DTI signal model contains no CSF

Exploring the role of apolipoprotein ε4 in progressive myoclonic epilepsy type 1

Epileptic Disorders, EarlyView.
Abstract Objective Progressive myoclonic epilepsy type 1 (EPM1) is a neurodegenerative disease caused by biallelic variants in the cystatin B (CSTB) gene. Despite a progressive course, phenotype severity varies among patients, even within families. We studied the potential role of APOE ε4 in modifying phenotypic diversity in EPM1, given its established

Modeling, Evaluation, and In Vivo Estimation of Muscle Cell Diameter With the Random Permeable Barrier Model: Correlation With Subject Characteristics and Isometric Torque. [PDF]

NMR Biomed
We evaluated the random permeable barrier model (RPBM) through simulations, model fitting, and in vivo analysis of 100 healthy adults. Simulations showed that stable estimates of muscle cell diameter and membrane permeability require constraining τ and fixing D0 at ~0.9 of axial diffusivity at long diffusion times.

Efficacy of neurosurgical interventions for epilepsy in polymicrogyria: A systematic review

Epilepsia Open, EarlyView.
Abstract Polymicrogyria (PMG) is a rare malformation of cortical development (MCD) characterized by abnormal neuronal architecture, often associated with epilepsy. Neurosurgical interventions have been explored, but their effectiveness remains a subject of ongoing research and debate.

Neuropsychological correlations with fornix and hippocampus in temporal lobe epilepsy demonstrated with diffusion tensor imaging

Epilepsia Open, EarlyView.
Abstract Objective Memory dysfunction is a common disabling comorbidity in temporal lobe epilepsy (TLE) and hippocampal sclerosis (HS). While bilateral fornix diffusion abnormalities have been reported in TLE using diffusion tensor imaging (DTI), the impact of fornix pathology on cognitive outcomes remains unclear.
