Abstract:
15mm~2)of dural sac cross-sectional area to values smaller than 75 mm~2 was found during examination in axial loading,or if a suspected disc herniation,narrow lateral recess,narrow intervertebral foramen,or intraspinal synovial cyst changed to being obvious at the axial loading examination,they were regarded as additional information.Results After axial loading CT examination,AVI was found in 16 of 40 patients.A significant decrease of dural sac area was found in 13 patients.Intervertebral disc herniation was more severe in 7 patients,lateral recess or interverbral foramen narrowed in 4 patients,no intraspinal synovial cyst was found.After axial loading MRI examination,AVI was found in 19 of 60 patients.A significant decrease of dural sac area was found in 13 patients.Intervertebral disc herniation became severe in 10 patients,lateral recess or interverbral foramen narrowed in 8 patients,no intraspinal synovial cyst was found.AVI was found in 32 of 79(40.5%)patients with sciatica and 2 of 20(10.0%)patients with low back pain(?~2=7.45 P
