Detecting dopaminergic neuronal degeneration using diffusion tensor imaging in a rotenone-induced rat model of Parkinson's disease: fractional anisotropy and mean diffusivity values

Neural Regeneration Research, 2017
Dopamine content in the basal ganglia is strongly associated with the degree of dopaminergic neuron loss in the substantia nigra pars compacta. Symptoms of Parkinson's disease might not arise until more than 50% of the substantia nigra pars compacta is ...

Nucleus Accumbens Fractional Anisotropy and Children’s Body Mass Index: Moderating Role of Race and Family Income [PDF]

International Journal of Epidemiologic Research, 2022
Background and aims: The nucleus accumbens (NAcc) functional and morphometric features may influence children’s body mass index (BMI). Recent evidence, however, suggests that the function and structure of the NAcc may have different predictive abilities ...

Transient increase of fractional anisotropy in reversible vasogenic edema [PDF]

Journal of Cerebral Blood Flow & Metabolism, 2016
Brain vasogenic edema, involving disruption of the blood-brain barrier, is a common pathological condition in several neurological diseases, with a heterogeneous prognosis. It is sometimes reversible, as in posterior reversible encephalopathy syndrome, but often irreversible and our current clinical tools are insufficient to reveal its reversibility ...

Fractional Anisotropy changes in Parahippocampal Cingulum due to Alzheimer’s Disease [PDF]

Scientific Reports, 2020
AbstractCurrent treatments for Alzheimer’s disease are only symptomatic and limited to reduce the progression rate of the mental deterioration. Mild Cognitive Impairment, a transitional stage in which the patient is not cognitively normal but do not meet the criteria for specific dementia, is associated with high risk for development of Alzheimer’s ...

A template-based procedure for determining white matter integrity in the internal capsule early after stroke

NeuroImage: Clinical, 2014
The integrity of descending white matter pathways, measured by fractional anisotropy from DW-MRI, is a key prognostic indicator of motor recovery after stroke.

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

PLoS 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.

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

Journal 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 ...

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

PLoS 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 ...

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

Psychiatry 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
