High-resolution and functional magnetic resonance imaging of the brachial plexus using an isotropic 3D T2 STIR (Short Term Inversion Recovery) SPACE sequence and diffusion tensor imaging.

摘要: This technical note demonstrates the relevance of isotropic 3D T2 turbo-spin-echo (TSE) sequence with short-term inversion recovery (STIR) and variable flip angle RF excitations (SPACE: Sampling Perfection Application optimized Contrasts using different Evolutions) for high-resolution brachial plexus imaging. The was used in 11 patients diagnosis pathologies involving primary secondary tumors, six volunteers. We show that STIR imaging is not only a reliable alternative to 2D imaging, but it also better evaluates anatomy, nerve site compression pathology plexus, especially depict space-occupying tumors along its course. Finally, due appropriate contrast we describe how 3D-STIR can be as mask fused fraction anisotropy (FA) maps calculated from diffusion tensor (DTI) data plexus.
