Voxel-based morphometry in Alzheimer’s disease

Expert Review of Neurotherapeutics, 2008
Recent morphometric MRI studies have investigated brain volume abnormalities associated with the diagnosis of Alzheimer's disease (AD) using voxel-based morphometry (VBM). This technique allows the assessment of gray matter volumes in subjects with AD or related conditions compared with healthy controls in an automated fashion, across the whole brain ...

Cerebellar voxel-based morphometry in essential tremor

Journal of Neurology, 2022
Imaging studies investigating cerebellar gray matter (GM) in essential tremor (ET) showed conflicting results. Moreover, no large study explored the cerebellum in ET patients with resting tremor (rET), a syndrome showing enhanced blink reflex recovery cycle (BRrc).To investigate cerebellar GM in ET and rET patients using voxel-based morphometry (VBM ...

Voxel-based morphometry and epilepsy

Expert Review of Neurotherapeutics, 2010
Voxel-based morphometry is an automated technique for MRI analyses, developed to study differences in brain morphology and frequently used to study patients with diverse disorders. In epilepsy, it has been used to investigate areas with reduction or increase of gray and white matter, in different syndromes (i.e., temporal lobe epilepsy, focal cortical ...

Voxel-based morphometry in narcolepsy

Sleep Medicine, 2005
Voxel-based morphometry (VBM) is a magnetic resonance imaging (MRI)-based indirect volumetry, which allows the investigation of the entire brain without restriction of predefined regions-of-interest. Recent studies using this technique reported controversial results in patients with narcolepsy.In this study, 12 patients with narcolepsy according to the

Voxel Based Morphometry

2007
At its simplest, voxel-based morphometry (VBM) involves a voxelwise comparison of regional gray matter ‘density’ between two groups of subjects. Density here refers to the relative amount of gray matter and should not be confused with cell packing density (number of cells per unit volume of neuropil).

Voxel-based morphometry of disgust proneness

Neuroscience Letters, 2012
This voxel-based morphometry study investigated whether the personality trait disgust proneness is associated with gray matter volume (GMV) of distinct brain regions implicated in disgust processing. We analyzed brain structural data from 99 healthy women, who had rated their tendency to experience disgust for different disgust domains (offensive food,

Voxel-Based Morphometry in Frontotemporal Dementia

Human Physiology, 2020
Frontotemporal dementia (FTD) is a clinically, genetically and pathologically heterogenous neurodegenerative disorder. FTD is characterized by a focal atrophy, which makes it a promising candidate for study using voxel-based morphometry (VBM). Visual assessment of magnetic resonance imaging of the brain is subjective and often depends on the researcher’

Voxel-based morphometry analyses in Alzheimer's disease

2013 IEEE 3rd Portuguese Meeting in Bioengineering (ENBENG), 2013
Alzheimer's disease (AD) is a neurodegenerative disease recognized as one of the most important medical problems affecting the elderly. It is characterized by an irreversible loss of neurons which is mostly pronounced in the grey matter and specifically in the hippocampus. The aim of this paper is to identify alterations in grey matter in MRI images of
