This atlas will provide a roadmap of normal sonographic anatomy of the musculoskeletal system with optimized images that emphasize spatial relationships and three-dimensional orientation. It will help novices acquire pattern recognition skills to resolve images into their anatomic components by pairing ultrasound scans with comparable MRI images and drawings, and enhance familiarity with musculoskeletal anatomy as it appears on ultrasound imaging for practitioners at any level. Taking a sectioned approach, the author presents a visual baseline for evaluating tendon, muscle, ligament, and nerve problems in the upper extremity, lower extremity, and cervical regions.
