Application of the Spiral CT Scan with MPR Reconstruction in the Degenerative Lumbar Spinal Stenosis Clinical Diagnosis

  • Objective: To investigate the performance of spiral CT scan and its clinical significance for the degenerative lumbar spinal stenosis diagnosis.Methods: The CT scan data from190 patients with the clinical symptoms of degenerative lumbar spinal stenosis were retrospectively analyzed.Results: CT scan showed that bulging disc/prominent fate postal vertebroplasty,vertebral spondylolisthesis and facet hypertrophy,ligamentum flavum hypertrophy,ossification of posterior longitudinal ligament to the central spinal canal sagittal diameter and smaller transverse Drive,lateral recess,foraminal narrower manifestations are the major changes in the degenerative spinal stenosis.We found that 19 cases with typeⅠ,central spinal stenosis;97 cases with typeⅡof spinal nerve root canal stenosis,lateral spinal stenosis;74 cases with typeⅢor mixed type(Ⅰ,Ⅱ-type) among the 190 patients.Spinal stenosis mainly happened at the L4-L5 and L5-S1.Conclusion: Spiral CT scan combined with the MPR reconstruction of interesting regions is highly sensitive to the discovery,evaluation and diagnosis of degenerative spinal.
