An MSK (musculoskeletal) ultrasound scan uses high-frequency sound waves to produce real-time images of muscles, tendons, ligaments, nerves, joints and soft tissues. It helps diagnose tears, sprains, inflammation, bursitis and fluid collections, and can guide injections or aspirations. The exam is non-invasive, painless, radiation-free and often performed dynamically to assess movement and tendon function.

MSK shoulder pain refers to pain arising from the musculoskeletal structures of the shoulder—muscles, tendons, ligaments, bones, cartilage and the joint capsule. Common causes include rotator cuff tendinopathy, bursitis, frozen shoulder, arthritis, sprain or overuse. It typically causes local pain, stiffness and reduced range of motion. Management often includes activity modification, physiotherapy, pain relief, injections and, rarely, surgery.

Ultrasound (sonography) uses high-frequency sound waves to create images of internal structures, often captured as static or cine images. Dynamic ultrasound specifically means real-time imaging during movement or functional tests, allowing visualization of structures while the patient moves or with applied stress. Dynamic studies reveal intermittent problems (e.g., tendon subluxation, impingement) that static images can miss and can guide procedures.

An ultrasound is a general imaging technique using high-frequency sound waves to visualize organs, blood flow and pregnancies. An MSK (musculoskeletal) ultrasound is a specialized application focusing on muscles, tendons, ligaments and joints; it uses high-frequency linear probes for detailed, superficial imaging, dynamic and comparative assessment, and often guides injections or procedures. MSK exams prioritize soft-tissue resolution and movement over deep-organ views.

MSK (musculoskeletal) refers to the body's muscles, bones, joints and the related clinical specialty. MRI (magnetic resonance imaging) is an imaging technique. They are not the same: MSK describes an anatomical system or specialty, while an MRI is a tool that can image MSK structures. An "MSK MRI" means an MRI scan focused on musculoskeletal tissues.

Yes. High resolution ultrasound can detect many peripheral nerve problems by showing nerve swelling, compression, discontinuity, scarring, neuromas and increased cross sectional area. It allows dynamic assessment and guides procedures. Ultrasound is operator dependent, less effective for deep or central nerves, and does not replace electrodiagnostic tests, which remain essential to evaluate nerve function.
