What Is Musculoskeletal (MSK) Ultrasound?

It is a diagnostic, non-invasive exam that allows high-resolution, real-time image evaluation of anatomical structures such as muscles, tendons and ligaments.

Why We Use MSK Ultrasound

  • Offers the payer a cost-effective alternative to MRI
  • Allows for dynamic examination which may detect abnormalities that are present only with joint positioning not obtainable with MRI
  • Useful when MRIs are contraindicated (metal implants, claustrophobia, etc.)
  • Provides visual guidance for improved accuracy during interventional procedures

Benefits of MSK Ultrasound

  1. Sonography is capable of producing results similar to those of MRI when performed
    by an experienced examiner.
  2. MSK Ultrasound (MSKUS) provides detailed depiction of superficial structures. It is also portable and less expensive.
  3. Interventional procedures such as joint aspiration can be guided with sonography.
  4. Dynamic examination of sonography may detect abnormalities that are present only with joint positioning not obtainable with MRI.
  5. MSKUS is useful when MRI's are contraindicated (metal implants, claustrophobia, etc).
  6. Superficial tendons and muscles can be easily depicted at high resolution. Sonography should be considered when a tendon abnormality is clinically suspected.
  7. MSKUS allows differentiation between full-thickness and partial-thickness tendon
    tears with greater ease than MRI.
  8. MSKUS sensitivity in diagnosing partial-thickness tears (in rotator cuff) is 93%.
  9. Tendons demonstrate a fine fibrillar echotexture by sonography and appear
    hyperechoic relative to muscle.
