Herniated Disc: AI-Powered MRI Detection of Protrusions & Extrusions

AI-powered herniated disc detection on spine MRI. Classify disc protrusions, extrusions, and sequestrations with nerve root compression grading. 4 AI models analyze disc morphology and foraminal stenosis in parallel.

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.
