Isotropic q-space Analytical map using 3D Diffusion MR Imaging

摘要: A q-space diffusion MR imaging is able to detect microstructure (10μm ∼ ) dynamically. Recently this method suggested as investigating neuronal generation and degeneration in spinal cord. The data sets are measured by two-dimensional (2D) multi-slice imaging. In order perform 2D imaging, it necessary have a few millimeters of slice thickness gap. Multi-slice an isotropic voxel the submicrometer range difficult. While on other hand, three-dimensional (3D) has advantage very thin slices with no gap (contiguous slices), allows acquisition small compared For detecting microstructural changes neuron, should be 3D which voxel. purpose study was examine diffusion-weighted MP-RAGE sequence (3D-DWI) for plant phantom. post-processing, analysis were performed we had several analytic volume map fresh celery (average displacement, zero-displacement probability, kurtosis). This accomplished get high resolution phantom strongly reflected restriction. We would now like go develop applying rat cord effectiveness vivo.
