AB0789 APPLICATIONS OF LOW-FIELD MAGNETIC RESONANCE IMAGING IN A RHEUMATOLOGY DEPARTMENT

Background: Low-field MRI (LF-MRI) is a useful Imaging technique for the diagnosis and in follow-up of high-impact rheumatologic pathology 1 . However, use not widespread due to high cost other techniques such as Musculoskeletal sonography 2 The Rheumatology Unit HUVM owns (ECO /MRI) standardized protocol LF-MRI 3 , which performed by rheumatologist applied routine clinical practice. We describe patterns general rheumatologists their Objectives: Perform an analysis department assessment joint inflammatory activity. Correlate results analyses patients without or with unclear diagnosis. Methods: Retrospective using medical records referred from January June 2018. main variables collected were reason referral well previous final after LR-MRI. An evaluation on usefulness made twelve months later establish Results: global population studied 114 LF-MRI. 81 females (71%). 80% diagnostic 40% Rheumatoid Arthritis (RA), 24% Psoriatic (PAs), 16% rheumatic diseases, remaining 20% most frequent reasons were: 1) A total (female male) was activity prior change treatment 2) subclinical optimized treatment. 23 (16 female; 7 male), differential diagnosis: arthralgias, 6 suspected psoriatic arthritis, undiagnosed inflammation, diagnosis, juvenile idiopathic arthritis (JIA), tendinitis.
