Joint microwave radiometry for inflammatory arthritis assessment

open access: yesRheumatology, 2019
Abstract Objectives Increased in-depth joint temperature measured by the rapid, easy-to-perform microwave radiometry (MWR) method may reflect inflammation, even in the absence of clinical signs. We hypothesized that MWR is useful for RA and spondyloarthritis patients’ assessment.
