Results In healthy subjects, L2-L5 nerves were displayed clearly by MRN, with a round or ellipse ganglion of 3-6 mm in diameter, and smooth stick-like nerve root and trunk, 2-5 mm in diameter. The signal intensity was higher in ganglion than nerve root or trunk. 40% of nerve root sheath was surrounded by small amount of cerebrospinal fluid, Femoral nerve was displayed in all subjects, while only 83.3% of obturator nerve and 43.3% of lumbosacral trunk were manifested. Lamellar blurred hyper-signal intensity was seen around 80.9% of lumbar plexus in GBS, but none in CIDP.
