Diffusion MRI (dMRI) has proven to be a useful imaging approach for both clinical diagnosis
and research investigating the microstructures of nervous tissues, and it has helped us to …

This article gives an overview of microstructure imaging of the brain with diffusion MRI and
reviews the state of the art. The microstructure‐imaging paradigm aims to estimate and map …

Parkinson disease is characterized by dopaminergic cell loss in the substantia nigra of the
midbrain. There are various imaging markers for Parkinson disease. Recent advances in …

Parkinson disease (PD) is a progressive disorder characterized by dopaminergic
neurodegeneration in the brain. The development of parkinsonism is preceded by a long …

The differential diagnosis of parkinsonian syndromes is considered one of the most
challenging in neurology and error rates in the clinical diagnosis can be high even at …

In diffusion MRI (dMRI), microscopic diffusion anisotropy can be obscured by orientation
dispersion. Separation of these properties is of high importance, since it could allow dMRI to …

Background Neuroimaging studies help us better understand the pathophysiology and
symptoms of Parkinson's disease (PD). In several of these studies, diffusion tensor imaging …

Background Cognitive deficits are among the main disabling symptoms in COVID-19
patients and post-COVID syndrome (PCS). Within brain regions, the hippocampus, a key …

Neuroaxonal pathology is a main determinant of disease progression in multiple sclerosis;
however, its underlying pathophysiological mechanisms, including its link to inflammatory …

The incidence of neurodegenerative diseases has shown an increasing trend. These
conditions typically cause progressive functional disability. Identification of robust …
