Functional diffusion tensor imaging at 3 Tesla

In a previous study we reported on a non-invasive functional diffusion tensor imaging (fDTI) method to measure neuronal signals directly from subtle changes in fractional anisotropy along white matter tracts. We hypothesized that these fractional anisotropy changes relate to morphological changes of glial cells induced by axonal activity. In the present study we set out to replicate the results...

Combined Functional Magnetic Resonance Imaging and Diffusion Tensor Imaging in

Diffusion-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....

Propagation 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...
