389 Fronto-parietal white matter integrity and neurometabolic profiles in medication-naïve first-episode psychosis

open access: yesJournal of Clinical and Translational Science
Objectives/Goals: In psychosis spectrum disorders, diffusion tensor imaging studies consistently report reduced fractional anisotropy in the superior longitudinal fasciculus, a major tract linking frontal and parietal cortices, yet the neurochemical ...

Micro-computed tomography derived anisotropy detects tumor provoked deviations in bone in an orthotopic osteosarcoma murine model. [PDF]

open access: yesPLoS ONE, 2014
Radiographic imaging plays a crucial role in the diagnosis of osteosarcoma. Currently, computed-tomography (CT) is used to measure tumor-induced osteolysis as a marker for tumor growth by monitoring the bone fractional volume.

Altered Cerebellar White Matter Integrity in Patients with Mild Traumatic Brain Injury in the Acute Stage.

open access: yesPLoS ONE, 2016
Background and purposeImaging studies of traumatic brain injury demonstrate that the cerebellum is often affected. We aim to examine fractional anisotropy alteration in acute-phase mild traumatic brain injury patients in cerebellum-related white matter ...

Using Diffusion Tensor Imaging to Evaluate Microstructural Changes and Outcomes after Radiofrequency Rhizotomy of Trigeminal Nerves in Patients with Trigeminal Neuralgia. [PDF]

open access: yesPLoS ONE, 2016
Trigeminal neuralgia is characterized by facial pain that may be sudden, intense, and recurrent. Our aim was to investigate microstructural tissue changes of the trigeminal nerve in patients with trigeminal neuralgia resulting from neurovascular ...

Brain volumetric and microstructural correlates of executive and motor performance in aged rhesus monkeys

open access: yesFrontiers in Aging Neuroscience, 2012
The aged rhesus macaque exhibits brain atrophy and behavioral deficits similar to normal aging in humans. Here we studied the association between cognitive and motor performance and anatomic and microstructural brain integrity measured with 3T magnetic ...

Orthogonal invariant sets of the diffusion tensor and the development of a curvilinear set suitable for low-anisotropy tissues. [PDF]

open access: yesPLoS ONE, 2013
We develop a curvilinear invariant set of the diffusion tensor which may be applied to Diffusion Tensor Imaging measurements on tissues and porous media.

Differential fractional anisotropy abnormalities in adolescents with ADHD or schizophrenia [PDF]

open access: yesPsychiatry Research: Neuroimaging, 2010
Schizophrenia and Attention-Deficit/Hyperactivity Disorder (ADHD) are associated with similar deficits in working memory, attention, and inhibition. Both disorders also involve abnormalities of white matter integrity, possibly reflecting neural communication disruptions. There are likely some regional white matter abnormalities that underlie the common

Microstructural injury to the optic nerve with vigabatrin treatment in West syndrome: A DTI study

open access: yesScientific Reports
To evaluate optic nerve injury associated with vigabatrin treatment in children with West syndrome using diffusion tensor imaging. Thirty-five children with West syndrome (aged 9 days–22 months) were retrospectively analyzed and grouped as follows: (1 ...
