Musculoskeletal ultrasound is increasingly being used by radiologists, rheumatologists, podiatrists, orthopedic surgeons, emergency medicine physicians, and physiatrists. The advantages of this imaging modality include wide availability of the equipment, the ability to perform dynamic imaging during joint motion, lower cost compared with computed tomography (CT) or magnetic resonance (MR) imaging, direct correlation with the site of pain, portability, and the ability to provide guidance during procedures such as joint aspiration and injection. The use of musculoskeletal ultrasound will likely only increase, given mounting pressures for cost containment.
