The anatomy of lumbosacral plexus (LSP) is complex, patients with trauma, neoplasms, or infection may experience motor weakness, sensory loss, and/or debilitating pain. Accurate and fast MRN scanning is an invaluable tool for evaluation of LSP diseases. In this study, the feasibility and performance of compressed sensing (CS) in scanning LSP was investigated and compared with conventional 3D-FFE with principles of the selective excitation technique. The results show that 3D-FFE with CS could reduce scan time obviously, influence image quality mildly, and meet clinical diagnosis.
