Spinal Stenosis: AI-Powered MRI Assessment
Upload your spine MRI for AI assessment of central and foraminal stenosis severity. Comprehensive grading and measurement analysis.
Overview
Spinal stenosis is the narrowing of the spinal canal, lateral recesses, or neural foramina, resulting in compression of the spinal cord or nerve roots. It most commonly affects the lumbar spine (causing neurogenic claudication) and cervical spine (causing myelopathy). Causes include degenerative changes, disc herniations, ligamentum flavum hypertrophy, and facet joint arthropathy. Our AI consortium evaluates stenosis at each level, grades severity, and identifies the contributing anatomical factors.
Common Symptoms
- Neurogenic claudication: leg pain and weakness with walking that improves with sitting
- Pain relieved by leaning forward (shopping cart sign)
- Bilateral buttock and leg heaviness
- Balance difficulties and wide-based gait (cervical myelopathy)
- Hand clumsiness and difficulty with fine motor tasks (cervical)
- Bladder or bowel dysfunction in severe cases
Key Imaging Findings
- Central canal narrowing with AP diameter measurement
- Lateral recess stenosis with nerve root compression
- Foraminal stenosis with nerve root impingement
- Ligamentum flavum hypertrophy contributing to stenosis
- Facet joint hypertrophy and synovial cysts
- Disc bulging as a component of stenosis
- Spinal cord compression with or without T2 signal changes (myelopathy)
Frequently Asked Questions
How is spinal stenosis severity graded on MRI?
Stenosis severity can be graded by several methods. For the lumbar spine, cross-sectional area and morphologic grading (normal, mild, moderate, severe) are commonly used. For cervical stenosis, the Torg-Pavlov ratio and cord compression are assessed. Our AI evaluates stenosis severity at each spinal level.
