This atlas provides high quality ultrasound images of musculoskeletal, mechanical, autoimmune, and inflammatory disorders encountered in rheumatology and other musculoskeletal clinic practices. Standard scanning conventions of joint regions with pertinent high-quality anatomic illustrations are used to facilitate understanding of sonographic images. Useful scanning pearls and pitfalls encountered in daily clinical practice are highlighted in each chapter. The atlas summarizes the role of ultrasonography in various rheumatologic conditions, identification of elemental sonographic lesions, classic examples of sonography in various classification criteria and grading systems for the diagnosis and management of selected rheumatic conditions. Expert authors provide case-based presentations of sonographic pathology. Supplementary video clips demonstrating common ultrasound-guided procedures performed in rheumatology, as well as dynamic ultrasonography are included. This is an ideal guide for rheumatologists and musculoskeletal providers incorporating ultrasound into their clinical practice.
