About

To observe the relationship between the activity of rheumatoid arthritis and popliteal/epitrochlear lymph node morphology and the drainage of hand/foot superficial lymphatic vessels

Full description

Rheumatoid Arthritis patients and health participants will be recruited in our research. Then the classification of American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) 2009 will be used to identify rheumatoid arthritis patients. The measurement of disease activity are Disease Activity Score 28 (DAS28) combined with the synovitis, bone edema and bone erosion of hand and wrist detected by magnetic resonance (MR) and Doppler ultrasound (DUS).The morphology of lymph node in popliteal/epitrochlear are scanned by 3-dimensional MR and DUS. The drainage of hand/foot superficial lymphatic vessels are detected in sight of near infrared ray (NIR) with the applying of Indocyanine Green (ICG) subcutaneously. We'll conduct correlation analysis to reveal the relationship between the activity of Rheumatoid Arthritis and lymph nodes morphology and lymphatic vessels drainage.
