Diffusion Tensor Imaging in Schizophrenia

Biological Psychiatry, 2006
Alignment of white matter axons as inferred from diffusion tensor imaging has indicated changes in schizophrenia in frontal and frontotemporal white matter.Diffusion tensor anisotropy and anatomical magnetic resonance images were acquired in 64 patients with schizophrenia and 55 normal volunteers.

Diffusion Tensor Imaging

2021
Diffusion tensor imaging (DTI) is an advanced imaging technique which enables quantification of anisotropic diffusion (i.e., restricted or preferential diffusion to one particular direction) in terms of direction and magnitude on a voxel-by-voxel basis. Serial calculation of anisotropic diffusion in neighboring voxels can provide the information on the

Diffusion Tensor Imaging of the Spinal Cord

Magnetic Resonance Imaging Clinics of North America, 2021
Spinal cord often is regarded as one of the last territories in the central nervous system where diffusion tensor imaging (DTI) can be used to probe white matter architecture. This article reviews current progress in spinal cord DTI, starting with anatomic properties and technical challenges that make spinal cord DTI a difficult task.

Diffusion Tensor Imaging

2020
Diffusion tensor imaging (DTI) is a powerful magnetic resonance imaging (MRI) technique that enables the measurement of the structural integrity of neural tissue. DTI allows for the visualisation of changes within neural tracts in conditions such as stroke, brain tumours, multiple sclerosis, Parkinson’s disease, Alzheimer’s disease and epilepsy.

Robust tensor estimation in diffusion tensor imaging

Journal of Magnetic Resonance, 2011
The signal response measured in diffusion tensor imaging is subject to detrimental influences caused by noise. Noise fields arise due to various contributions such as thermal and physiological noise and sources related to the hardware imperfection. As a result, diffusion tensors estimated by different linear and non-linear least squares methods in ...

Diffusion Tensor Imaging of Peripheral Nerves

Seminars in Musculoskeletal Radiology, 2015
Diffusion tensor imaging (DTI) is a powerful MR imaging technique that can be used to probe the microstructural environment of highly anisotropic tissues such as peripheral nerves. DTI has been used predominantly in the central nervous system, and its application in the peripheral nervous system does pose some challenges related to imaging artifacts ...

Diffusion tensor imaging of subependymal heterotopia

Epilepsy Research, 2012
A magnetic resonance (MR) diffusion tensor imaging (DTI) study was performed in a newborn with bilateral subependymal heterotopia (SE). White matter fractional anisotropy (FA), axial diffusivity (AD) and radial diffusivity (RD) were compared to values obtained in four newborns with moderate perinatal asphyxia and normal MRI findings.

Diffusion and Diffusion Tensor Imaging in Brain Cancer

Seminars in Radiation Oncology, 2011
Conventional magnetic resonance imaging provides important information on the structure of tumors, but new imaging tools are emerging that provide more detailed functional information on tumor biology. In particular, diffusion-weighted imaging (DWI) is sensitive to the tumor microenvironment so it may serve as a prognostic biomarker and an indicator of

Diffusion tensor imaging of brain development

Seminars in Fetal and Neonatal Medicine, 2006
Understanding early human brain development is of great clinical importance, as many neurological and neurobehavioral disorders have their origin in early structural and functional cerebral organization and maturation. Diffusion tensor imaging (DTI), a recent magnetic resonance (MR) modality which assesses water diffusion in biological tissues at a ...
