Uncinate Fasciculus Findings in Schizophrenia: A Magnetic Resonance Diffusion Tensor Imaging Study
(American Psychiatric Publishing, 2002)
Objective: Disruptions in connectivity between the frontal and temporal lobes may explain some of the symptoms observed in schizophrenia. Conventional magnetic resonance imaging (MRI) studies, however, have not shown ...
Cingulate fasciculus integrity disruption in schizophrenia: a magnetic resonance diffusion tensor imaging study
(Elsevier BV, 2003)
Background: Evidence suggests that a disruption in limbic system network integrity and, in particular, the cingulate gyrus (CG), may play a role in the pathophysiology of schizophrenia; however, the cingulum bundle (CB), ...
Diffusion Tensor Imaging and Its Application to Neuropsychiatric Disorders
(Ovid Technologies (Wolters Kluwer Health), 2002)
Magnetic resonance diffusion tensor imaging (DTI) is a new technique that can be used to visualize and measure the diffusion of water in brain tissue; it is particularly useful for evaluating white matter abnormalities. ...
High-Resolution Line Scan Diffusion Tensor MR Imaging of White Matter Fiber Tract Anatomy
(2002)
Background and Purpose: MR diffusion tensor imaging permits detailed visualization of white matter fiber tracts. This technique, unlike T2-weighted imaging, also provides information about fiber direction. We present ...
Shape of caudate nucleus and its cognitive correlates in neuroleptic-naive schizotypal personality disorder
(Elsevier BV, 2004)
Background: We measured the shape of the head of the caudate nucleus with a new approach based on magnetic resonance imaging (MRI) in schizotypal personality disorder (SPD) subjects in whom we previously reported decreased ...
Spatial normalization of diffusion tensor MRI using multiple channels
(Elsevier BV, 2003)
Diffusion Tensor MRI (DT-MRI) can provide important in vivo information for the detection of brain abnormalities in diseases characterized by compromised neural connectivity. To quantify diffusion tensor abnormalities based ...
A review of diffusion tensor imaging studies in schizophrenia
(Elsevier BV, 2007)
Both post-mortem and neuroimaging studies have contributed significantly to what we know about the brain and schizophrenia. MRI studies of volumetric reduction in several brain regions in schizophrenia have confirmed early ...
White matter hemisphere asymmetries in healthy subjects and in schizophrenia: a diffusion tensor MRI study
(Elsevier BV, 2004)
Hemisphere asymmetry was explored in normal healthy subjects and in patients with schizophrenia using a novel voxel-based tensor analysis applied to fractional anisotropy (FA) of the diffusion tensor. Our voxel-based ...
Comparison of Single-Shot Echo-Planar and Line Scan Protocols for Diffusion Tensor Imaging
(Elsevier, 2004)
Rationale and Objectives: Both single-shot diffusion-weighted echo-planar imaging (EPI) and line scan diffusion imaging (LSDI) can be used to obtain magnetic resonance diffusion tensor data and to calculate directionally ...
DTI and MTR abnormalities in schizophrenia: Analysis of white matter integrity
(Elsevier BV, 2005)
Diffusion tensor imaging (DTI) studies in schizophrenia demonstrate lower anisotropic diffusion within white matter due either to loss of coherence of white matter fiber tracts, to changes in the number and/or density of ...
