Indocyanine green–enhanced imaging of antigen‐induced arthritis with an integrated optical imaging/radiography system

Abstract

Indocyanine green-enhanced optical imaging is a clinically applicable tool for detection of arthritic tissue. Using relatively high doses of indocyanine green, long-term enhanced fluorescence of arthritic joints can be achieved. This may facilitate simultaneous evaluations of multiple joints in a clinical setting. Fusion of indocyanine green-enhanced optical imaging scans with radiography increases anatomic resolution.
