A Pediatric Brain Template for Diffusion Tensor Imaging
Introduction Diffusion tensor imaging reveals detailed structural information about white matter tracts, and is increasingly used to study the pediatric population. It is highly desirable to construct age appropriate templates so the findings in patients could be reported using coordinates in a standard stereotaxic brain space, and at all brain locations the diffusion measures of an individual ...
متن کاملDiffusion tensor imaging: a review for pediatric researchers and clinicians.
Diffusion tensor imaging (DTI) is a magnetic resonance imaging technique that allows for the visualization and characterization of the white matter tracts of the brain in vivo. DTI does not assess white matter directly. Rather, it capitalizes on the fact that diffusion is isotropic (equal in all directions) in cerebral spinal fluid and cell bodies but anisotropic (greater in one direction than ...
متن کاملDiffusion-Weighted Imaging and Diffusion Tensor Imaging
Assessment of the integrity of the articular cartilage is considered key for the early diagnosis of osteoarthritis (OA). Diffusion-weighted imaging and diffusion tensor imaging have potential as biomarkers for cartilage composition and structure. The value of diffusion to detect compositional and structural changes in the cartilage matrix has been shown in ex vivo experiments for several years....
متن کاملPropagation Framework for Diffusion Tensor Imaging via Diffusion Tensor Error Propagation Framework for Diffusion Tensor Imaging via Diffusion Tensor Representations
This preprint is made available because the published work cited below had several infelicities due to production error, i.e., awkward layout of equations and font styles. The conversion from the Words document here to IEEE TMI format was a mess. Abstract An analytical framework of error propagation for diffusion tensor imaging (DTI) is presented. Using this framework, any uncertainty of intere...
متن کاملEvaluation of White Matter Tracts in Autistic Individuals: A Review of Diffusion Tensor Imaging Studies
Introduction: Many cognitive and social deficits in autism are caused by abnormal functional connections between brain networks, which are manifested by impaired integrity of white matter tracts. White matter tracts are like the "highways" of the brain, which allow fast and efficient communication in different areas of the brain. The purpose of this article is to review the results of autism st...
