Novel molecular imaging compounds that detect neuroinflammation in the brain of multiple sclerosis (MS) patients have been developed by researchers at the Washington University School of Medicine in Missouri, and may help to uncover the triggers of such inflammation and to better evaluate new disease treatments. The study, “Development and in vivo evaluation of three F-18 labeled S1P1 ligands as PET tracers for MS,” was recently presented at the 2016 Society of Nuclear Medicine and Molecular Imaging (SNMMI) Annual Meeting in San Diego, California.
