Noninvasive imaging of macrophages in rheumatoid synovitis using ¹¹C‐(<i>R</i>)‐PK11195 and positron emission tomography

Abstract

11C-(R)-PK11195 PET imaging allows noninvasive in vivo imaging of macrophages in rheumatoid synovitis and possibly even in subclinical synovitis. Noninvasive visualization of macrophages may be useful both for detecting early synovitis and for monitoring synovitis activity during treatment.
