A review of magnetic resonance imaging and diffusion tensor imaging findings in mild traumatic brain injury
(Springer Science + Business Media, 2012)
Mild traumatic brain injury (mTBI), also referred to as concussion, remains a controversial diagnosis because the brain often appears quite normal on conventional computed tomography (CT) and magnetic resonance imaging ...
Thalamo-frontal white matter alterations in chronic schizophrenia
(Wiley-Blackwell, 2009)
Diffusion tensor imaging (DTI) and fiber tractography are useful tools for reconstructing white matter tracts (WMT) in the brain. Previous tractography studies have sought to segment reconstructed WMT into anatomical ...
Neuroimaging in repetitive brain trauma
(BioMed Central, 2014)
Sports-related concussions are one of the major causes of mild traumatic brain injury. Although most patients recover completely within days to weeks, those who experience repetitive brain trauma (RBT) may be at risk for ...
Reduced fractional anisotropy and axial diffusivity in white matter in 22q11.2 deletion syndrome: A pilot study
(Elsevier BV, 2012)
Individuals with 22q11.2 deletion syndrome (22q11.2DS) evince a 30% incidence of schizophrenia. We compared the white matter (WM) of 22q11.2DS patients without schizophrenia to a group matched healthy controls using ...
Directional functions for orientation distribution estimation
(Elsevier BV, 2009)
Computing the Orientation Distribution Function (ODF) from High Angular Resolution Diffusion Imaging (HARDI) signals makes it possible to determine the orientation of fiber bundles of the brain. The HARDI signals are samples ...
Multi-tensor investigation of orbitofrontal cortex tracts affected in subcaudate tractotomy
(Springer Science + Business Media, 2014)
Subcaudate tractotomy (SCT) is a neurosurgical lesioning procedure that can reduce symptoms in medically intractable obsessive compulsive disorder (OCD). Due to the putative importance the orbitofrontal cortex (OFC) in ...
Diffusion imaging of mild traumatic brain injury in the impact accelerated rodent model: A pilot study
(Informa UK Limited, 2017-06-19)
PRIMARY OBJECTIVE: There is a need to understand pathologic processes of the brain following mild traumatic brain injury (mTBI). Previous studies report axonal injury and oedema in the first week after injury in a rodent ...
A prospective longitudinal volumetric MRI study of superior temporal gyrus gray matter and amygdala–hippocampal complex in chronic schizophrenia
(Elsevier BV, 2009)
A progressive post-onset decrease in gray matter volume 1.5 years after first hospitalization in
schizophrenia has been shown in superior temporal gyrus (STG). However, it is still controversial whether progressive volume ...
Two Methods for Validating Brain Tissue Classifiers
(Springer Science + Business Media, 2005)
In this paper, we present an evaluation of seven automatic brain tissue classifiers based on level of agreements. A number of agreement measures are explained, and we show how they can be used to compare different segmentation ...
