Ankle & Foot MRI Scan: Complete Guide

An ankle MRI scan provides detailed imaging of the complex structures within the ankle and foot, including bones, ligaments, tendons, cartilage, and soft tissues. The ankle is one of the most commonly injured joints, and MRI is essential for diagnosing conditions that are invisible on X-ray. Lola Health offers private ankle and foot MRI scans at over 150 UK centres.

What an Ankle & Foot MRI Scan Shows

• Ligament injuries — tears or sprains of the lateral ligaments (ATFL, CFL), deltoid ligament, and syndesmotic ligaments (high ankle sprain).
• Tendon pathology — Achilles tendon tears or tendinopathy, posterior tibial tendon dysfunction, peroneal tendon injuries.
• Stress fractures — commonly in the metatarsals, navicular, or calcaneus, often missed on X-ray.
• Osteochondral lesions — damage to the cartilage and underlying bone on the talar dome.
• Plantar fasciitis — thickening and inflammation of the plantar fascia.
• Morton's neuroma — thickening of the nerve between the toes causing pain.
• Bone marrow oedema — a sign of stress reaction, infection, or inflammatory arthritis.
• Ankle arthritis — osteoarthritis or inflammatory arthritis affecting the ankle joint.
• Tarsal tunnel syndrome — compression of the tibial nerve behind the medial malleolus.
• Ganglion cysts and soft tissue masses — benign or occasionally malignant growths around the foot and ankle.

When You Might Need an Ankle & Foot MRI

• Persistent ankle pain after a sprain that is not resolving
• Chronic Achilles tendon pain or suspected tear
• Foot pain in runners or athletes (suspected stress fracture)
• Heel pain (plantar fasciitis assessment)
• Forefoot pain (Morton's neuroma assessment)
• Ankle instability or recurrent sprains
• Swelling or stiffness in the foot or ankle
• Pain not explained by X-ray findings
• Pre-surgical planning for ankle or foot procedures

How to Prepare

• Metal check: Remove ankle bracelets, toe rings, and any metal from the foot area. Declare any metal implants.
• Clothing: Wear loose trousers that can be rolled above the knee. Remove shoes and socks.
• No fasting required.
• Arrive 15 minutes early.

What to Expect During the Scan

1. Positioning: Lie on your back or sit with your foot placed in a dedicated foot/ankle coil.
2. Duration: 25 to 40 minutes.
3. Keeping still: Avoid moving your foot and toes during the scan.
4. Contrast: Rarely needed for standard ankle/foot scans, but may be used for specific conditions.
5. After: Resume normal activities. Continue following any injury management advice.

How Much Does an Ankle & Foot MRI Cost?

Ankle & Foot MRI and Blood Testing

• Uric acid: Gout is one of the most common causes of inflammatory foot pain, particularly affecting the big toe. Blood tests can confirm or rule out gout.
• Inflammatory markers (CRP, ESR): Elevated levels may suggest inflammatory arthritis, infection, or gout affecting the foot and ankle.
• Rheumatoid factor and anti-CCP: Rheumatoid arthritis frequently affects the small joints of the foot.
• Vitamin D: Deficiency increases the risk of stress fractures and bone pain.
• HbA1c: Diabetes can cause foot problems including Charcot joint and neuropathy.
• Full blood count: Helps rule out infection or systemic conditions.

Start with a Lola Health blood test to check your inflammation markers, uric acid, and vitamin D. If results suggest further investigation, a foot & ankle MRI can provide the structural detail your blood results can't show. Peak Insights 70 covers these markers across 70 biomarkers.

Frequently Asked Questions

Can an MRI detect a stress fracture?

Yes. MRI is far more sensitive than X-ray for detecting stress fractures, which may only show bone marrow oedema in the early stages.

Is the scan painful?

No. The scan is painless, although the foot may need to be positioned in a specific way within the coil.

Do I need a referral?

No. Book directly through Lola Health.

Can MRI show Achilles tendon tears?

Yes. MRI clearly visualises partial and complete Achilles tendon tears, as well as tendinopathy.

How quickly do I get results?

Typically within a few working days.

Should I stop exercising before the scan?

If you have a suspected stress fracture, follow your clinician's advice regarding activity. The scan itself does not require you to stop exercising beforehand.

Can both feet be scanned at the same time?

Usually each foot is scanned separately for optimal image quality. Discuss with the scanning centre if both sides need assessment.
