Imaging of Lymphatic Vessels in People With Rheumatoid Arthritis (RA)
Recruiting now Phase 1 NCT05197530
Run by University of Rochester · for 18 and older · All sexes
What this study is about
Lymphatic transport was previously examined by these investigators using Near InfraRed Indocyanine Green fluorescence imaging (NIR-ICG) of the upper extremities. They established reliable and reproducible methodologies in RA patients. The purpose of this phase 2 pilot is to study RA disease progression and effectiveness as well as the mechanism of action of clinical interventions using established NIR-ICG methodologies in previous studies.
