Figure 2: Tractography of the corticospinal tract (CST) for SE and SSFP with identical thresholding (1000 fibers). Tracts reach the cortex more reliably in SSFP, whereas the SE tracts end where the CST crosses the superior longitudinal facsciculus (SLF) and CC.

High resolution diffusion-weighted imaging in fixed human brain using diffusion-weighted steady state free precession
High resolution diffusion tensor imaging and tractography of ex vivo brain specimens has the potential to reveal detailed fibre architecture not visible on in vivo images. Previous ex vivo diffusion imaging experiments have focused on animal brains or small sections of human tissue since the unfavourable properties of fixed tissue (including short T(2) and low diffusion rates) demand the use of...
متن کاملDiffusion tractography of post-mortem human brains: Optimization and comparison of spin echo and steady-state free precession techniques
Diffusion imaging of post-mortem brains could provide valuable data for validation of diffusion tractography of white matter pathways. Long scans (e.g., overnight) may also enable high-resolution diffusion images for visualization of fine structures. However, alterations to post-mortem tissue (T2 and diffusion coefficient) present significant challenges to diffusion imaging with conventional di...

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 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...
متن کاملDiffusion-prepared fast imaging with steady-state free precession (DP-FISP): a rapid diffusion MRI technique at 7 T.
Diffusion MRI is a useful imaging technique with many clinical applications. Many diffusion MRI studies have utilized echo-planar imaging (EPI) acquisition techniques. In this study, we have developed a rapid diffusion-prepared fast imaging with steady-state free precession MRI acquisition for a preclinical 7T scanner providing diffusion-weighted images in less than 500 ms and diffusion tensor ...
