Shear-wave elastographic ultrasound of metacarpophalangeal synovium in rheumatoid arthritis - A pilot study.

Introduction: Shear-wave elastographic ultrasound (SW-EUS) assesses the stiffness of human tissues. It is used in liver, thyroid and breast imaging but has not been studied in synovium. Soft tissues have a slower shear-wave velocity (SWV) than stiff tissues.
