Applications of Doppler Imaging in the Musculoskeletal System

Pathological conditions affecting the musculoskeletal system often result in alterations of regional blood flow. The assessment of a Doppler signal in inflammatory or infective processes complements the grayscale findings, helping to evaluate the severity of disease. Doppler imaging can also be used to determine therapeutic response or help guide injections. In addition, Doppler interrogation enables vascular characterization of solid masses. The presence of a Doppler signal can also help differentiate solid from cystic lesions. This article reviews the wide range of applications for Doppler imaging of the musculoskeletal system.
