Summary
This early-phase study tested a new imaging tracer called [18F]F-AraG in 9 patients who had or were at high risk for graft-versus-host disease (GVHD) after a stem cell transplant. The tracer is designed to highlight activated T cells, which cause GVHD. Researchers compared the PET scan results with biopsies to see if the tracer could accurately identify GVHD sites. The study was completed but did not include healthy volunteers as originally planned.
