Imaging in rheumatology: ultrasafe + ultrasure = ultrasound

Technological advances in ultrasonography (US) in recent years has allowed for improvements to the imaging quality of gray-scale ultrasound and the development of more advanced forms of this imaging technique such as 3D and Doppler US. These improvements mean that US now has an accepted place in rheumatology not only in diagnosis, but also in the determination of disease progression and pathology and in facilitating guidance of interventional therapies. The increasing use of US-guided intervention by rheumatologists in the last 20 years is evidenced by the almost exponential increase in the number of publications in the relevant subjects.
