Herniated Disc: AI-Powered MRI Assessment
Upload your spine MRI for AI-powered disc herniation detection, classification, and nerve compression assessment. Private browser-based analysis.
Overview
A herniated disc occurs when the nucleus pulposus extrudes through a defect in the annulus fibrosus, potentially compressing adjacent neural structures. Disc herniations are classified by morphology (protrusion, extrusion, sequestration), location (central, paracentral, foraminal, extraforaminal), and level. MRI is the gold standard for evaluating disc herniations and their effect on the spinal cord and nerve roots. Our AI consortium provides detailed characterization of herniation type, size, location, and associated nerve compression using established nomenclature.
Common Symptoms
- Radiating pain along the affected nerve distribution (sciatica for lumbar)
- Numbness or tingling in the leg, foot, arm, or hand
- Muscle weakness in the affected nerve territory
- Pain worsening with sitting, bending, or coughing (lumbar)
- Neck pain with arm radiation (cervical)
- Decreased reflexes in the affected nerve distribution
Key Imaging Findings
- Disc material extending beyond the vertebral body margin
- Protrusion: broad-based disc extension with intact outer annulus
- Extrusion: disc material extending through the annulus with narrow neck
- Sequestration: free disc fragment separated from parent disc
- Nerve root compression or displacement
- Spinal cord compression with or without signal changes (cervical/thoracic)
- Pfirrmann grading of disc degeneration
Frequently Asked Questions
What is the difference between a disc bulge, protrusion, and extrusion?
A bulge involves more than 50% of the disc circumference. A protrusion is a focal extension with a broad base. An extrusion has a narrow neck with material extending beyond the base. A sequestration is a free fragment. Our AI classifies disc herniations according to the standardized NASS nomenclature.
Does a herniated disc always need surgery?
No. Many disc herniations improve with conservative treatment. Our AI provides objective characterization of herniation size, type, and nerve compression severity, which are factors in treatment decisions. Surgical consultation is recommended for progressive neurological deficits or cauda equina syndrome.
