Lumbar Central Canal Stenoses, Neural Foraminal Stenoses
Conditions
Brief summary
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.

Eligibility
Inclusion criteria
* Age ≥ 18 years * Outpatient status * Scheduled for routine supine CT myelography
Exclusion criteria
* Inpatient status * Presence of metallic lumbar spinal hardware * History of osseous metastatic disease involving the lumbar spine * Acute traumatic injury involving the lumbar spine * Pregnancy * Participant body habitus exceeding the scanner's safe operational limits (e.g., gantry/bore size clearance, table weight capacity) as defined by the device manufacturer. * Inability to tolerate CT scanning (e.g., severe pain, unable to stand independently for an extended period)
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Does upright CT imaging change management plans for patients with lumbar spinal stenosis | 1 week | To determine whether upright CT imaging changes the management plan (yes or no) for patients with lumbar spinal stenosis. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Spine measurements | 1 day | Objective measurements at different angles (mm) will be taken of the spine. |
| Severity grading of central canal stenosis | 1 day | Severity grading (mild, moderate, severe) of central canal stenosis in the spine. |
| Severity grading of neural foraminal stenosis | 1 day | Severity grading (mild, moderate, severe) of neural foraminal stenosis in the spine. |
| Presence or absence of nerve root compression | 1 day | Presence or absence of nerve root compression in the spine. |
| Presence or absence of disc bulges | 1 day | Presence or absence of disc bulges in the spine. |
