Diagnostic ultrasound produces real-time images using high-frequency sound waves. It assesses tendons, muscles, joint effusions, and blood flow without radiation, and permits dynamic examination during movement.
Image quality depends heavily on operator technique.
Alternative Names:
Sonography, Diagnostic Ultrasound
Why it Matters?
Ultrasound's dynamic capability allows assessment during movement that static imaging cannot provide, which is useful for tendon and rotator cuff evaluation. Its principal limitation in litigation is operator dependence, since the study cannot be independently reinterpreted the way MRI images can. A defense expert reviewing an ultrasound is largely dependent on the original operator's captured images and description.
