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

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

Parkinson's disease (PD) is the second most common neurodegenerative disease after
Alzheimer's disease (AD). It is characterized by a progressive loss of dopaminergic neurons …

There has been an increasing prevalence of neurodegenerative diseases with the rapid
increase in aging societies worldwide. Biomarkers that can be used to detect pathological …

Pathology of neurodegenerative diseases can be correlated with intra-neuronal as well as
extracellular changes which lead to neuronal degeneration. The central nervous system …

Understanding the neuropathological underpinnings of mental disorders such as
schizophrenia, major depression, and bipolar disorder is an essential step towards the …

Introduction Diffusional kurtosis imaging (DKI) is a more sensitive technique than
conventional diffusion tensor imaging (DTI) for assessing tissue microstructure. In particular …

Purpose Conventional motion and eddy-current correction, where each diffusion-weighted
volume is registered to a non diffusion-weighted reference, suffers from poor accuracy for …

The ability to image the whole brain through ever more subtle and specific
methods/contrasts has come to play a key role in understanding the basis of brain …

Diffusion MRI (dMRI) has become one of the most important imaging modalities for
noninvasively probing tissue microstructure. Diffusional Kurtosis MRI (DKI) quantifies the …
