Developments in digital ultrasonography (US) technology and the use of
high-frequency broadband transducers have increased the quality of US imaging,
particularly of superficial tissues. Thus, US, particularly color US or power
Doppler US, in which high-resolution transducers are used, has become an
important imaging modality in the assessment of rheumatic diseases. Furthermore,
therapeutic interventions and biopsies can be performed under US guidance during
the assessment of lesions. In this era of effective treatments, such as
biologics, improvements in synovial inflammation in rheumatoid arthritis as well
as changes in enthesitis in spondyloarthropathies, including ankylosing
spondylitis and psoriatic arthritis, can be monitored effectively using
gray-scale and/or power Doppler US. US is also a good imaging modality for
crystal arthropathies, including gout and pseudogout, in which synovitis,
erosions, tophi, and crystal deposition within or around the joint can be
visualized readily. Vascular and tenosynovial structures, as well as the salivary
glands, can be assessed with US in vasculitis and connective tissue disorders,
including systemic lupus erythematosus and Sjögren's syndrome. Current research
is focused on improving the sensitivity, specificity, validity, and
reproducibility of US findings. In this review, we summarized the role of US,
particularly power Doppler US, in rheumatic diseases and inflammation in
superficial tissues.
