Fiber Enhancement in Diffusion-Weighted MRI
Diffusion-Weighted MRI (DW-MRI) measures local water diffusion in biological tissue, which reflects the underlying fiber structure. In order to enhance the fiber structure in the DW-MRI data we consider both (convection-)diffusions and Hamilton-Jacobi equations (erosions) on the space R o S of 3D-positions and orientations, embedded as a quotient in the group SE(3) of 3D-rigid body movements. T...
متن کاملNeuronal Fiber Delineation in Area of Edema from Diffusion Weighted MRI
Diffusion Tensor Magnetic Resonance Imaging (DT-MRI) is a non invasive method for brain neuronal fibers delineation. Here we show a modification for DT-MRI that allows delineation of neuronal fibers which are infiltrated by edema. We use the Muliple Tensor Variational (MTV) framework which replaces the diffusion model of DT-MRI with a multiple component model and fits it to the signal attenuati...
متن کاملAre we expecting too much from the diffusion-weighted MRI?
(DW-MRI) is a method where the signal required to produce a MRI image is determined by the " mobility of water ". Diffusivity measurements have multiple components related to tissue cellularity and organization, integrity of the cell membranes, extracellular space tortuosity and perfusion (1). Until recent years, main limitation for the use of DWI in the body area wa the artefacts originating f...
متن کاملStructure Tensor Informed Fiber Tractography (STIFT) by combining gradient echo MRI and diffusion weighted imaging
Structural connectivity research in the human brain in vivo relies heavily on fiber tractography in diffusion-weighted MRI (DWI). The accurate mapping of white matter pathways would gain from images with a higher resolution than the typical ~2mm isotropic DWI voxel size. Recently, high field gradient echo MRI (GE) has attracted considerable attention for its detailed anatomical contrast even wi...
متن کاملDiffusion-weighted MRI: distinction of skull base chordoma from chondrosarcoma.
BACKGROUND AND PURPOSE Chordoma and chondrosarcoma of the skull base are rare tumors with overlapping presentations and anatomic imaging features but different prognoses. We hypothesized that these tumors might be distinguished by using diffusion-weighted MR imaging. MATERIALS AND METHODS We retrospectively reviewed 19 patients with pathologically confirmed chordoma or chondrosarcoma who unde...
