MRI of the Lumbar Spine (L‑Spine) is a highly detailed, radiation-free scan used to assess the lower back, spinal cord, nerves, discs, and surrounding structures.

Description of MRI Lumbar Spine (L-Spine)
MRI L‑Spine provides high-resolution images of the lumbar vertebrae, discs, spinal canal, nerve roots, ligaments, and soft tissues. Because MRI uses magnetic fields instead of radiation, it is safe and ideal for detecting subtle abnormalities that X-ray or CT may miss.
An MRI Lumbar Spine is commonly requested for:
- Lower back pain
- Sciatica or leg pain (radiculopathy)
- Disc bulges or herniations
- Spinal canal stenosis
- Nerve compression in the lower back
- Degenerative disc disease and arthritis
- Suspected cauda equina syndrome
- Trauma or fractures
- Spondylolisthesis (vertebral slippage)
- Infection or tumour assessment
- Post-surgical evaluation
MRI can also evaluate the spinal cord and cauda equina for inflammation, compression, or structural abnormalities. Some cases require contrast if infection, tumour, or prior surgery is involved.
At Advicon Imaging, lumbar spine MRI studies are performed on modern MRI systems with fast scanning protocols optimised for comfort and clarity. All Medicare-eligible MRI referrals are fully bulk-billed.
Additional Notes
Please notify staff if you experience severe symptoms such as bowel/bladder changes or loss of leg function, as these may indicate urgent conditions.
