Rheumatoid arthritis is a chronic inflammatory disease characterized by the development of osseous and cartilaginous damage .
The correct differentiation between a true erosion and other entities — then often called “ pseudoerosions”—is essential to avoid misdiagnosing rheumatoid arthritis and to correctly interpret the progress of the disease .
The aims of this systematic review were as follows : to create a definition and delineation of the term “ pseudoerosion ” , to point out morphological pitfalls in the interpretation of images , and to report on difficulties arising from choosing different imaging modalities .
Magnetic Resonance Imaging of the Rheumatic Foot According to the RAMRIS System Is Reliable
Objective . In rheumatology , magnetic resonance imaging ( MRI ) is predominantly applied in the assessment and outcome measurement of rheumatoid arthritis ( RA ) in h and s and wrists , leading to the development of the RAMRIS ( RA-MRI-Scoring ) system . It was initiated by the Outcome Measures in Rheumatoid Arthritis Clinical Trials ( OMERACT ) . The RAMRIS system has not been applied widely in the measurement of feet . We investigated the interreader and intrareader agreement of the RAMRIS scoring system in the assessment of feet in RA . Methods . Twenty-nine patients with RA who had radiological damage and /or arthritis underwent MRI .  Two experienced readers independently read both complete sets . One reader read 6 r and om sets after the initial session , in order to assess the intrareader agreement . For evaluation of the intrareader and interreader reliability , quadratic-weighted κ scores were calculated per joint and lesion . Results . For the forefeet , interreader scores were excellent , ranging from 0.77 ( bone edema ) to 0.95 ( bone erosion ) . Hindfoot interreader agreement scores were highest for erosion ( 0.90 ) and synovitis global score ( 0.88 ) , but edema and synovial thickness agreement were also acceptable ( 0.83 and 0.86 ) . Intrareader scores were on the whole slightly lower , but excellent . Conclusion . Reliability ( interreader and intrareader agreement ) in the assessment of the rheumatoid foot according to the RAMRIS method is excellent
