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 and aging
Neuroscience & Biobehavioral Reviews, 2006Magnetic resonance diffusion tensor imaging (DTI) is a non-invasive in vivo method for characterizing the integrity of anatomical connections and white matter circuitry and provides a quantitative assessment of the brain's white matter microstructure. DTI studies reveal age-related declines in white matter fractional ansiotropy (FA) in normal healthy ...

Peripheral nerve diffusion tensor imaging
Magnetic Resonance Imaging, 2004We examined if MR diffusion tensor imaging with fiber tracking could be performed on the sciatic nerve. In 3 healthy volunteers the proximal thigh was examined on a 1.5-Tesla MR-scanner with a 2-channel phased-array coil. Though inherently susceptible to motion, field inhomogeneities, and fast T(2)-relaxation of the diffusion imaging technique, the ...

Diffusion Tensor Magnetic Resonance Imaging
Journal of Neuro-Ophthalmology, 2006Molecular diffusion plays an important role in many biologic phenomena. The ability to study diffusion, therefore, is extremely useful in physiology and medicine. MRI offers a non-invasive window to diffusion, particularly water self-diffusion. MRI techniques, which provide diffusion sensitivity or quantitation (diffusion tensor MRI [DTI]), have found ...

Diffusion Tensor Imaging in Schizophrenia
Biological Psychiatry, 2005Diffusion tensor imaging (DTI) is a relatively new neuroimaging technique that can be used to examine the microstructure of white matter in vivo. A systematic review of DTI studies in schizophrenia was undertaken to test the hypothesis that DTI can detect white matter differences between schizophrenia patients and normal control subjects.EMBASE, PubMed,

Diffusion Tensor Imaging in Schizophrenia
Biological Psychiatry, 2006Alignment 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 of Peripheral Nerves
Seminars in Musculoskeletal Radiology, 2015Diffusion 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 in Neurofluids
Neuroimaging Clinics of North AmericaIn this review article, we describe the development and application of diffusion-based MR imaging methods for studying glymphatic physiology. Fluid exchange and solute transport are the 2 key components of the glymphatic system. Here we describe the use of low b-value imaging, free water fraction imaging, and diffusion time sensitization to leverage ...
