Attentional networks and cingulum bundle in chronic schizophrenia.
Thirty patients with chronic schizophrenia and 30 age-matched controls performed the Attention Network Test (ANT). A subset of the patient group (n=18) also had available magnetic resonance diffusion tensor imaging (DTI) measures of the cingulum bundle (CB) fractional anisotropy and volume. The patients showed a significantly different pattern of ANT performance, characterized primarily by decr...
متن کاملAltered cingulum bundle microstructure in autism spectrum disorder.
OBJECTIVE Here, we examined the cingulum bundle, a long-range white matter tract mediating dorsal limbic connectivity, using diffusion tensor imaging (DTI) tractography, in children and adolescents with autism spectrum disorder (ASD) versus controls. We hypothesised that cingulum bundle microstructure would be altered in ASD, based on evidence implicating abnormal white matter connectivity in t...
متن کاملThe relationship between cognitive function and high-resolution diffusion tensor MRI of the cingulum bundle in multiple sclerosis.
BACKGROUND Imaging can provide noninvasive neural markers of disease progression in multiple sclerosis (MS) that are related to behavioral and cognitive symptoms. Past work suggests that diffusion tensor imaging (DTI) provides a measure of white matter pathology, including demyelination and axonal counts. OBJECTIVES In the current study, the authors investigate the relationship of DTI measure...
متن کاملSeparation of Fiber Tracts within the Human Cingulum Bundle using Single-Shot STEAM DTI
The cingulum bundle is a complex white matter fiber tract of the human brain that comprises long association fibers, commissural fibers, and various U-fibers. It is located above the corpus callosum and interconnects limbic structures. A decline of the cingulum fiber integrity has been observed in patients with mental disorders such as schizophrenia. In this work a separation of the bi-hemisphe...
متن کاملFinsler Tractography for White Matter Connectivity Analysis of the Cingulum Bundle
In this paper, we present a novel approach for the segmentation of white matter tracts based on Finsler active contours. This technique provides an optimal measure of connectivity, explicitly segments the connecting fiber bundle, and is equipped with a metric which is able to utilize the directional information of high angular resolution data. We demonstrate the effectiveness of the algorithm f...
