Probe placement shifts the diagnosis to the point of evaluation. That's the appeal of MSK ultrasound: a sports medicine physician can image a rotator cuff tear, assess a Baker's cyst, or guide a subacromial injection in the same exam room where the patient was already sitting. No referral slip, no scheduling delay, no patient driving across town to an imaging center. The scan volume that follows a MSK machine into an orthopedic or sports medicine practice tends to be substantial enough to justify the investment in the first year of ownership, and our financing structures are built to reflect that front-loaded return.
Musculoskeletal ultrasound machines operate primarily at high frequencies. Linear-array transducers in the 5-18 MHz range, and for superficial structures sometimes above 20 MHz, are the tools of choice. That frequency range delivers the resolution needed to distinguish tendon fiber disruption, evaluate bursae, and characterize peritendinous fluid. The machines that excel at this work, particularly somewhere in the $60k–$180k band, are different instruments than a general abdominal or radiology ultrasound system, even if some platforms handle both.
