Anisotropic fractional diffusion tensor imaging.
Traditional diffusion tensor imaging (DTI) maps brain structure by fitting a diffusion model to the magnitude of the electrical signal acquired in magnetic resonance imaging (MRI). Fractional DTI employs anomalous diffusion models to obtain a better fit to real MRI data, which can exhibit anomalous diffusion in both time and space. In this paper, we describe the challenge of developing and empl...
متن کاملAnisotropic Acquisition and Analysis for Diffusion Tensor Magnetic Resonance Imaging
Diffusion tensor magnetic resonance imaging (DT-MRI) is a non-invasive imaging method for assessing the characteristics and organization of tissue microstructure. The diffusion tensor provides information about the magnitude, anisotropy, and orientation of water diffusion in biological tissues. In brain white matter, the direction of greatest diffusivity is typically assumed to be parallel to t...
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 کاملEnhancing quality in Diffusion Tensor Imaging with anisotropic anomalous diffusion filter
Introduction: Diffusion tensor imaging (DTI) is an important medical imaging modality that has been useful to the study of microstructural changes in neurological diseases. However, the image noise level is a major practical limitation, in which one simple solution could be the average signal from a sequential acquisition. Nevertheless, this approach is time-consuming and is not often applied i...
