Feasibility of diffusion tensor imaging of the brachial plexus using iZOOM

The brachial plexus is difficult to obtain diffusion tensor image (DTI) with good image quality due to the inhomogeneity of the magnetic field and motion artifacts. Zoom imaging based on 2D RF (iZoom) could both reduce the distortion dramatically and has better fat suppression effects. In this study, we compared DTI using conventional Zoom with that using iZoom for the brachial plexus and diffusion tractography with iZoom created higher mean length and fiber count than the conventional Zoom sequence, suggesting its feasibility as a new method for diffusion tensor imaging for the brachial plexus.
