Synopsis

Double Echo Steady-State (DESS) with water-selective excitation is a useful sequence to depict small nerves such as intracranial nerves, it would also be promising for visualizing lumbar nerves. Recently, accelerated qDESS sequence combined with compressed sensing sensitivity encoding (Compressed SENSE) has been proposed for further rapid knee morphological and quantitative imaging. In this study, we evaluate the feasibility of the accelerated qDESS sequence for visualization and quantification of the lumbosacral plexus within a short scan time.
