NODDI with dispersion anisotropy
PURPOSE This work presents a technique for estimating the dispersion anisotropy in neurite orientations, using Neurite Orientation Dispersion and Density Imaging (NODDI) [1]. NODDI is a diffusion MRI technique, recently developed to directly quantify the microstructural features (density and orientation dispersion) of neurites in vivo, in the human brain. The parameters it provides offer higher...
متن کاملNODDI-SH: a computational efficient NODDI extension for fODF estimation in diffusion MRI
Diffusion Magnetic Resonance Imaging (DMRI) is the only non-invasive imaging technique which is able to detect the principal directions of water diffusion as well as neurites density in the human brain. Exploiting the ability of Spherical Harmonics (SH) to model spherical functions, we propose a new reconstruction model for DMRI data which is able to estimate both the fiber Orientation Distribu...
متن کاملcomparison of mr images for age determination; t1 weighted images (t1wi) versus t2* weighted images (t2*wi)
purpose t1wi (t1 weighted image) was acquired in order to grade bone fusion following the studies by fifa (federation internationale de football associations). research using images other than t1wi has not been reported. the aim of this study is to evaluate the grade of epiphyseal fusion by t2* weighted images (t2*wi) and to investigate new findings on t2*wi as compared with t1wi. methods a tot...
متن کاملMR Spin Behavior During RF Pulses: T2 vs. T2' Relaxation
Introduction: We investigate the behavior of the MR magnetization vector during RF pulses in the presence of rapid transverse relaxation. The transverse relaxation is divided into two separate mechanisms: Homogeneously broadened lines which resulting in irreversible T2 amplitude decay, and inhomogeneously broadened lines resulting in dephasing and in principle refocusable T2’. While the two dif...
متن کاملCardiac and Hepatic T2*-Weighted Magnetic Resonance Imaging
Abstract Background Iron overload is the main transfusion related side effects in patients with transfusion dependent hemoglobinopathies. Severe iron deposition in tissues leads to organ dysfunction. Many organs can be affected such as heart, liver, and endocrine organs. Cardiac failure and liver fibrosis are the consequent of Iron overload in transfusion dependent hemoglobinopathy. Magne...
