چکیده
3D diffusion-weighted steady-state free precession imaging (3D DW-SSFP) with isotropic resolution was performed to delineate structures of the human lumbosacral plexus (LSP). 3D DW-SSFP clearly revealed detailed anatomy of the LSP and its branches. Our data suggest that the sequence based on 3D DW-SSFP can be used for high-resolution MR imaging of the peripheral nervous system.

Background Access to appropriate images of fetal brain can greatly assist to diagnose of probable abnormalities. The aim of this study was to compare the suitability of T2-True Fast Imaging with Steady State Free Precession (T2-TRUFI), and T2-Half-Fourier Acquisition Single-Shot Turbo Spin-Echo (T2- HASTE( magnetic resonance imaging (MRI) to extract the fetal brain using the level set algorithm...
متن کاملSteady-State Free Precession (SSFP) Diffusion Imaging Using 3D Rotating Spirals (3DRS)
INTRODUCTION 3D diffusion imaging has been an appealing but challenging topic over the last decade. It provides good properties such as isotropic resolution, higher SNR efficiency, and less inflow effect. However, it also suffers from long scan time and consequently more severe motion artifacts. Compared with traditional spinecho diffusion weighted imaging (DWI) method, steady-state free preces...
متن کاملIn-Vivo evaluation of cartilage repair using Steady-State Diffusion Weighted Imaging
Introduction Various MR imaging sequences have given proof of their ability to visualize ultra structural components and to reveal the biochemical composition of cartilage. One encouraging approach in the means of cartilage grading is the use of diffusion weighted sequences [1,2]. Conventional DWI based on spin-echo (SE) sequences is relatively insensitive to susceptibility effects, but diffusi...

Susceptibility-weighted imaging (SWI) has continued to develop into a powerful clinical tool to visualize venous structures and iron in the brain and to study diverse pathologic conditions. It is a new art which evaluates and exploits the properties of blood, iron and other tissues. It is a magnitude or filtered phase images or combination of both, obtained with high-resolution 3D fully velocit...
