What advances in ultrasound technology have contributed to its usefulness for MSK imaging?
With the introduction of higher frequency transducers and other techniques such as compound imaging, we are now able to see structures with improved clarity and can appreciate subtle pathology. One example of this is the use of ultrasound to evaluate peripheral nerves, and the technology allows us to see individual nerve fascicles. Q: Why do you believe the benefits of ultrasound for MSK outweigh concerns about diminishing MR use? A: Applications for musculoskeletal ultrasound relative to MRI can be viewed in two categories. The first category includes applications where ultrasound complements MRI or is the preferred examination. Examples of this include the use of ultrasound to dynamically evaluate nerve or tendon dislocation and its use when a patient cannot have an MRI (e.g., a patient with specific implants or foreign bodies). The second category includes applications where ultrasound and MRI are equally effective, such as evaluation for tendon abnormalities, including the rotator
