What an MSK sonographer images, the exams they perform, the conditions those exams find, and the credential and settings involved.
Musculoskeletal sonography — MSK for short — images the soft tissues that move the body: muscles, tendons, ligaments, joints, nerves, and the bursae that cushion them. Its defining strength is that it can image these structures in motion, while the patient moves a joint, which a still image from another test cannot show. It is a more recent and more focused area of sonography than abdominal or OB/GYN.
What it images
MSK studies cover muscles, tendons, ligaments, joints, nerves, bursae, and superficial soft tissues. Common regions are the shoulder, elbow, wrist and hand, hip, knee, and ankle and foot (ARDMS Musculoskeletal content outline; AIUM musculoskeletal practice parameter).
The common studies
- Region-specific joint ultrasound. The shoulder is the most common, where the rotator cuff is evaluated (ARDMS MSKS content).
- Dynamic imaging. Scanning while the patient moves the joint — an MSK-specific advantage over a still MRI image (AIUM MSK parameter).
- Procedure assistance. MSK sonographers may assist with ultrasound-guided injections and aspirations (U.S. Bureau of Labor Statistics, May 2024).
The conditions it helps find
MSK ultrasound evaluates rotator-cuff tears, calcium deposits and wear in tendons (tendinitis and tendinosis), tendon and ligament tears, joint fluid and inflammation of the joint lining, bursitis, ganglion cysts and soft-tissue masses, nerve entrapment such as carpal tunnel syndrome, muscle tears, and foreign bodies in tissue (ARDMS MSKS content; AIUM MSK parameter).
The credential
- RMSKS — Registered Musculoskeletal Sonographer, issued by the American Registry for Diagnostic Medical Sonography (ARDMS). The path requires the Sonography Principles and Instrumentation (SPI) physics exam plus the MSKS exam, within five years (ARDMS, 2024).
MSK is a comparatively newer and narrower credential. Unlike cardiac and vascular, it has no direct equivalent from Cardiovascular Credentialing International or the American Registry of Radiologic Technologists — the RMSKS is the principal dedicated credential. Licensing and Certification covers the credentialing bodies.
Where the work happens
MSK sonographers work in sports-medicine and orthopedic clinics, rheumatology practices, physical-medicine and rehabilitation settings, and radiology departments, with some in outpatient imaging centers. The BLS does not break out a separate MSK employer profile; the work falls under the general sonography settings.
Pay and outlook
MSK work sits within the general diagnostic medical sonographers occupation (code 29-2032): a median wage of $89,340 and 13 percent projected growth from 2024 to 2034 (BLS, May 2024). MSK is a growing point-of-care area, but the BLS does not publish an MSK-specific wage.
