Methods and materials
MRI scans were assessed in 54 UA (undiffrenciated arthritis) patients,
according to the OMERACT rheumatoid arthritis MRI scoring system (RAMRIS) recommended by the European League Against Rheumatism.
It included assessment of the presence of erosions (Fig.
1) ,
bone marrow oedema (Fig.2),
thickening (Fig.
3 and Fig.
5) and enhancement (Fig.
4 and Fig 6) of the synovium after i.v.
contrast medium injection as a sign of synovitis in the wrist area and MCP joints.
The ultrasound assessment included detection of joint and tendon sheath effusion,
synovial hypertrophy and hypervascularity.
Based on the subsequent clinical and laboratory findings after at least 3 months follow-up,
18 patients were diagnosed as rheumatoid arthritis (RA) and 11 as spondyloarthropathy (SpA); for 12 patients the diagnosis remained UA until the end of follow-up period and in 13 cases the diagnosis of arthritis was not confirmed.
Subsequently the ROC analysis was performed to find out the predictive value of radiological parameters.
