Ultrasound (US) is an imaging technique that uses high frequency sound waves to create images of the body. It does not expose you to radiation. The ultrasound transducer sends sound waves through the skin and soft tissues which then reflect back to itself creating a black and white picture of the anatomical structure we are interested in. Using ultrasound increases safety and efficacy of injection procedures by confirming anatomy and needle placement, verifying medication dispersion and avoiding venipuncture or tendon rupture. Ultrasound guided injections are performed in the doctor’s office for several diagnoses related to soft tissue injuries or joint pain. Common diagnoses include bursitis, tendonitis, epicondylitis and arthralgia.
