In this book recognized world-renowned expert authors expose the state of the art on musculoskeletal ultrasound elastography. Low cost, wide dissemination and accuracy in the evaluation of the musculoskeletal structures, nerves, periosseous soft parts, vascular structures, together with the possibility of performing real time dynamic studies, made the ultrasound technique widely spread among sonographers and musculoskeletal radiologists. Each chapter presents a description of the elastographic semiotics of the main pathologies of the musculoskeletal system and soft tissue, images that represent both routine and more complex clinical cases in a practical and schematic way and summary tables on the characteristics in terms of elasticity found in the main pathologies. A wealth of color images as well as dynamic images and tables complete the book, that will be a useful tool for sonographers , radiologists, orthopedists, sports medicine specialists wishing to expand their knowledge on ultrasound elastography.
