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