voxel-based morphometry, magnetic resonance imaging, statistical parametric mapping, gray matter, white matterIn recent years, a whole-brain unbiased objective technique, known as voxel-based morphometry (VBM), has been developed to characterise brain differences in vivo using structural magnetic ...
Voxel-based morphometry--the methods. At its simplest, voxel-based morphometry (VBM) involves a voxel-wise comparison of the local concentration of gray matter between two groups of subjects. T... J Ashburner,KJ Friston - 《Neuroimage》 被引量: 1.4万发表: 2000年 Voxel-based morphometry of...
The use of various magnetic resonance imaging (MRI) techniques (for example, functional MRI, voxel-based morphometry (VBM) and diffusion-tensor imaging) to understand human neurological physiology and pathology is now ubiquitous. With the exception of functional MRI1, few of these methods have under...

Statistical analysis of anatomical maps in a stereotaxic space has been shown to be a useful tool in population-based studies for quantifying local anatomical differences or changes, without a priori assumptions about the location and extent of the regions of interest. This paper presents an extensio...
resonance imaging (MRI) studies.Materials and Methods Using the separation in atrophy rate between cohorts of cognitively normal elderly subjects and patients with Alzheimer's disease (AD) as the gold standard, we evaluated 1) different methods of computing volume change; 2) different methods...doi...
In the current study, we used voxel-based morphometry (VBM) to investigate the structural neural basis of trait modesty in Chinese college students. VBM results showed that higher trait modesty score was associated with lager regional gray matter volume in the dorsomedial prefrontal cortex, right ...
