Back pain is one of the most common reasons people visit a GP — and one of the most frustrating to live with when it lingers. An X-ray, if you've had one, may have shown nothing remarkable. That doesn't mean there's nothing to find; it means X-rays have real limits when it comes to soft tissue. A spine MRI looks at an entirely different layer of detail.
What a spine MRI can show
MRI is far more revealing than X-ray for the structures most likely to be causing persistent back or leg pain:
- Intervertebral discs — bulges, prolapses and degeneration
- Nerve roots — compression or irritation that may explain sciatica or referred leg pain
- Spinal canal — stenosis (narrowing) that can cause pain on walking
- Facet joints — arthritis or inflammation in the small joints along the spine
- Spinal cord and surrounding structures — for those with neurological symptoms
Because it uses no ionising radiation, MRI is safe for repeated use and for a wide range of patients.
When is a spine MRI worth considering?
A scan isn't necessary for every episode of back pain, but it's often the right next step if:
- Pain has persisted for six weeks or more without meaningful improvement
- You have pain, numbness or tingling running down one or both legs (sciatica)
- You've noticed weakness in the legs or changes in bladder or bowel function (seek urgent advice for these)
- You want a clear diagnosis before deciding between physiotherapy, an injection or specialist referral
- You've tried treatment but it isn't working and you're not sure why
What's included at Northwest Health
There's no need for a GP referral before booking. Our clinic GP conducts a pre-scan review to confirm MRI is appropriate for your symptoms and safe for you personally. The scan covers the relevant section of your spine — cervical (neck), thoracic (mid-back) or lumbar (lower back) — and takes approximately 30–45 minutes.
Every scan is reported by a consultant radiologist, and the written report is usually ready within three to five working days. If you'd like two spinal regions scanned in the same visit — for example, lumbar and cervical — that's covered by our two-area price.
How much does a private spine MRI cost?
- 1 spinal region — £400 (includes GP review and consultant radiologist report)
- 2 spinal regions — £600
- 3 areas (Silver) — £775
Northwest Health is CQC-registered, and all imaging is reported by qualified consultant radiologists — not automated software.
From scan to next steps
A spine MRI report won't solve your back pain on its own, but it gives you and your care team a factual starting point. Some people find a structural explanation leads to targeted physiotherapy that finally works. Others find reassurance that nothing serious is driving the pain — which matters too.
