An MRI of the shoulder shows detailed images of bones, joint cartilage, the rotator cuff tendons and muscles, labrum, ligaments, and bursae. It detects tendon tears, inflammation, impingement, joint degeneration (arthritis), bone marrow changes, fractures, fluid or effusion, and soft-tissue masses. MRI also evaluates post‑operative changes and subtle injuries not seen on X‑ray, guiding diagnosis and treatment planning.

A shoulder MRI typically ranges widely depending on country, facility, and whether contrast is used. In the US expect roughly $400–$3,500 (higher with contrast or outpatient facility). In the UK it’s free on the NHS or about £200–£700 privately. In India prices are often ₹2,000–10,000. Additional fees for contrast, radiologist reporting, and consultations may apply; insurance can lower out‑of‑pocket cost.

A shoulder MRI typically takes about 20–40 minutes of scanning time, though the full appointment often lasts 30–60 minutes including setup, positioning and paperwork. If contrast dye is used, add roughly 10–15 minutes for injection and extra imaging. Time varies by scanner type and number of sequences, so bring prior images and arrive early for check-in.

A 3T shoulder MRI with a dedicated shoulder protocol gives the best overall image quality. For rotator cuff, tendons, bursae and bone, a standard MRI is usually sufficient. If a labral tear, subtle intra‑articular lesion or instability is suspected, an MR arthrogram (contrast injected into the joint) is more sensitive and preferred.

MRI can detect many causes and consequences of shoulder nerve injury — for example nerve compression, traumatic lesions, masses, or muscle denervation (edema, atrophy). Standard MRI may not directly show very small peripheral nerve fiber damage; MR neurography and high-resolution sequences improve visualization. Electrophysiological tests (EMG/nerve conduction studies) are often used alongside imaging to confirm, localize, and assess severity.

Costs vary widely by country and facility. In the U.S., a shoulder MRI typically ranges from about $500 to $3,000 (commonly $1,000–$2,000 without insurance). In the U.K. it’s free on the NHS; private scans usually cost £150–£700. In India, prices commonly run ₹2,000–₹12,000 depending on machine and contrast. Additional fees (contrast, radiologist report) may apply.
