Abstract：Objective To explore the feasibility of CT on multiple plane reconstruction of the lesion 5th lumber nerve at the same slice, providing the basis for the clinical diagnosis of L5 neuropathy. Methods 30 patients with of L5 neuropathy and 20 normal adults were scanned by GE Light Speed 16 and PHILIPS iCT 256-slice CT, reconstructed with their own workstations (GE, ADW4.1 and Philips Brilliance 3.0) to observe the normal anatomy and basic disease of L5 nerve. Results 20 cases (40 sides)of normal L5 nerve were symmetrically displayed from starting point to margin of psoas major and 15 cases (75%) to upper sacroiliac joint in oblique coronal plane. 20 cases (100%)of L5 nerve were displayed from starting to sacroiliac joint plane and 6 cases (30%) were shown to sacral plexus or upper sciatic nerve by internally rotating oblique coronal plane. In all of the L5 neuropathy, there were travel direction and tension status change in 16 cases(24 sides), shrink in 12 cases(18 sides), localized thickening 3 cases(5 sides), fuzzy 15 cases(18 sides) and distorted in 1 case(1 side). L5 neuropathy involved L5-S1 disc lateral protrusion with bone hyperplasia (10 cases), hypertrophy of transverse process of 5th lumbar vertebra (5 cases), L5 spondylolysis (8 cases), L5 vertebral compression fracture (3 cases) and pelvic malignancies(4 cases). Conclusions HRCT multiple plane reconstruction technique at the same slice can provide a valuable diagnosis basis for L5 neuropathy.
