Individuals who abuse substances often differ from nonusers in their brain structure.
Substance abuse and addiction is often associated with atrophy and pathology of grey …

Diffusion tensor imaging studies have provided evidence for white matter (WM) alterations in
cocaine users. While polysubstance use is a widespread phenomenon among cocaine …

Background Tobacco use remains the most preventable cause of death; however, its effects
on the brain, and particularly white matter, remain elusive. Previous diffusion tensor imaging …

Diffusion tensor imaging, a novel technique with an increased capability of detecting
abnormalities in the white matter, has increasingly been employed in the study of the biology …

Individuals with alcohol use disorders show white matter abnormality relative to normal
samples, but differences in white matter profiles have not yet been investigated as a function …

Brain imaging using conventional magnetic resonance imaging (MRI) has revealed that
several brain structures in people with a history of chronic alcohol dependence are smaller …

Studies in cocaine-dependent human subjects have shown differences in white matter on
diffusion tensor imaging (DTI) compared with non-drug-using controls. It is not known …

Aims In the last years, refined magnetic resonance diffusion tensor imaging (DTI) methods
have become available to study microstructural alterations in the human brain. We …

Background: Postmortem studies report degradation of brain white matter microstructure in
chronic alcoholism, but until recently, in vivo neuroimaging could provide measurement only …

Objectives: Fractional anisotropy (FA) via diffusion tensor imaging (DTI) can quantify the
white matter integrity. Exposure to addictive drugs, such as alcohol, cocaine …
