When prefer MRI over MSK ultrasound?

When there is suspicion of bone injury, marrow edema, deep structures (acetabulum, nucleus pulposus), deep intra-articular lesions or complex pre-surgical planning. US excels at tendons, soft tissue and dynamic study.

Useful for guided injections?

Yes — US guidance for intra-articular, peritendinous and bursal injections increases accuracy and safety compared to blind technique.

When to use

MSK US evaluates tendons, muscles, ligaments, bursae and superficial collections. Real-time dynamic study is a key advantage — useful for impingement, instability, partial tears and procedure guidance. Limited for bone and deep structures; MRI completes the workup when indicated.

What to evaluate

Tendons: thickness, echotexture, contours, tendinosis/partial or full tear signs.
Muscles: fibrillar architecture, tears, hematomas, muscular herniation.
Bursae: distention, content, Doppler vascularity.
Joint: effusion, synovitis, loose bodies, cartilage (limited).
Superficial collections and masses: size, echogenicity, vascularity.
