Dynamic Changes in the Dural Sac Cross-Sectional Area on Axial Loaded MR Imaging: Is There a Difference between Degenerative Spondylolisthesis and Spinal Stenosis?

摘要

Axial loaded MR imaging, which can simulate the spinal canal of patients in a standing position, demonstrates a significant reduction of the DCSA compared with conventional MR imaging and provides valuable imaging findings in the assessment of the lumbar spinal canal. The purpose of this study was to compare the DCSA on axial loaded MR imaging between patients with DS and SpS.
