研究概览
简要总结
The purpose of this prospective study is to compare the diagnostic utility of standing (upright, weight-bearing) CT myelography with standard supine CT myelography for the evaluation of lumbar central canal and neural foraminal stenoses. This study aims to determine whether upright positioning provides additional diagnostic information in patients unable to undergo MRI, with the goal of improving assessment and management of degenerative lumbar spine disease.
