Overview
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.
Interventions
- Radiation Upright CT
Upright CT Myelography
Primary outcome measures
- Does upright CT imaging change management plans for patients with lumbar spinal stenosis [Time frame: 1 week]
Secondary outcome measures (6)
- Spine measurements [Time frame: 1 day]
- Severity grading of central canal stenosis [Time frame: 1 day]
- Severity grading of neural foraminal stenosis [Time frame: 1 day]
- Presence or absence of nerve root compression [Time frame: 1 day]
- Presence or absence of disc bulges [Time frame: 1 day]
- Presence or absence of herniations [Time frame: 1 day]
Eligibility criteria
