Session Time: 9:00AM-10:30AM
To evaluate the agreement between ultrasound (US), whole body magnetic resonance imaging (WBMRI) and clinical assessment of joint inflammation and enthesitis in rheumatoid arthritis (RA) patients, by comparison on joint/enthesis level and by evaluating the correlation between composite scores at
US, WBMRI and clinical assessment for tender joints (TJ) and swollen joints (SwJ) were performed in 19 RA patients (90% Women, median (range) age 55 (26-73), diseases duration 5.5 (1-42), SwJ(28) 5 (1-13), TJ(28) 7 (2-24) and DAS28-CRP 4.66 (3.48 -6.66))) fulfilling ACR 1987 criteria for RA. The 28 conventional joints, bilateral ankles and MTP 1-5, and the entheses of supraspinatus, gluteus muscles, quadriceps and Achilles tendon were assessed by WBMRI and US.
Joint inflammation by
To assess the total inflammatory burden, a composite score was established as sum scores for the 28 conventional joints for US (US28) and for 26 joints (WBMRI26) for WMBRI – same 28 joints
US28 and WBMRI26 sum scores showed good correlation rho= 0.72 (p=0.003) (Fig. 1), whereas US28 and WBMRI26 did not correlate with DAS28 CRP (rho=-0.26, p=0.28; rho=0.20, p=0.47 respectively).
Enthesitis was rare in RA
WBMRI and US sum scores of joint inflammation showed good correlation in RA patients but the agreement at joint level was variable. The agreement on enthesitis between MRI and US was low, but findings were minimal. No correlation with DAS28 was found for either modality.
