Sciatica imaging
Sciatica describes pain, numbness, or weakness that travels from the lower back through the buttock and down one leg along the sciatic nerve distribution. Imaging identifies the underlying cause — most often a herniated disc or spinal stenosis — and guides targeted treatment.
Affected anatomy
- Sciatic Nerve
- Lumbar Spine
- Sacral Nerve Roots
Also known as
- lumbar radiculopathy
- sciatic nerve pain
- nerve root compression
Imaging used for sciatica
MRI
Lumbar MRI is the preferred study for sciatica. It shows disc herniations, foraminal stenosis, and nerve root contact with high soft-tissue contrast.
CT
CT myelography or plain CT is used when MRI is unavailable or contraindicated, and provides good bony detail around the nerve roots.
