The value of ultrasound in rheumatology is supported by a consistent body of evidence. The number of studies has progressively increased documenting the interest for this imaging tool especially in the assessment of patients with chronic inflammatory arthritis (1,2). More than ten years have passed since ultrasonography was described as an evolving technique, and at present ultrasound equipment keeps on evolving. Probes with very high frequency (up to 22 MHz in greyscale and 14.3 MHz of Doppler frequency), volumetric probes with high-resolution linear transducers, fusion imaging, and dedicated software for automatic assessment of specific findings (such as intima media thickness at common carotids) are only the most representative technological developments which have already found an application in rheumatology described in recent publications (3-11).

New applications for research and clinical practice include the detection of submillimetric abnormalities at both joint and tendon levels in patients with early arthritis, the identification of very superficial tissues involvement due to changes of morphology, echostructure, elasticity, and perfusional status at dermal level in patients with psoriatic arthritis and systemic sclerosis, and the visualization of normal intra-articular blood flow in healthy subjects.

While hardware and software advances have been developed with the aim to improve ultrasound diagnostic abilities, the delay of the standardization process of musculoskeletal ultrasound in rheumatology was the main side effect.

In the near future, the high quality imaging of the current top systems will be available in portable machines, the quality-cost of the US equipment will keep on improving, and the connectivity between US machines and other systems will be enhanced and real-time streaming of ultrasound imaging will become of common use (12).
