MSK ultrasound is a new modality in our geographic area for imaging soft tissue around joints. It usues high frequency sound waves to generate an image using an ultrasound machine. There is no radiation or contrast needed. There is no claustrophobic apparatus and with the portability of today's ultrasound machines, they can be performed just about anywhere - including normal exam rooms, in the patient's home or even on the sports field. MSK is especially useful in sports injury - both for diagnosing abnormalites (tears, strains, sprains) as well as monitoring recovery. Some of the most common uses include rotator cuff tears and abnormailites, carpal tunnel syndrome, tennis elbow, runners and jumpers knee, ankle sprains, snapping hip syndrome, effusions and tendinitis. Much recent literature has been produced showing the benefots and even better acuracy of MSK ultrasound over MRI.
