Accelerated quantitative double echo steady state (qDESS), which is combined with Compressed SENSE is expected to improve visualization of the cervical nerve roots and brachial plexus. The purpose of this study was to optimize flip angle (FA) and spatial resolution (3D voxel size) of accelerated qDESS to visualize the small nerve roots and brachial plexus in the cervical spine. As a result, a combination of FA: 35 degree and voxel size: 0.8mm3 was the most appropriate parameters to demonstrate them while suppressing the background signals including the muscles, blood vessels, and cerebrospinal fluid.
