This book provides a detailed overview of RADIOLOGIA imaging of sport-related injuries of the lower extremity. The available literature focuses mainly on either clinical aspects or all imaging modalities and clinical aspects of sport-related pathologies, with little relevance on RADIOLOGIA. Indeed, recent advances in RADIOLOGIA technology, including high resolution, electronic, broadband transducers, have led to improved assessment of the musculoskeletal system, and RADIOLOGIA is now considered an optimal imaging technique to evaluate musculoskeletal sport-related injuries. Its advantages include the ability to perform dynamic examinations essential for many diagnoses, such as intrasheath instability of the peroneal tendons.Drawing on the author s over 30 years of experience in clinical praxis, this book highlights the great potential of the ultrasonographic evaluation of sports-related injuries and is entirely devoted to this technique.
