The peptide PET tracer ¹¹C-glycylsarcosine is a promising tumor-imaging agent and is superior to ¹⁸F-FDG for distinguishing between tumors and inflammatory tissue. In mice with tumor in the right hind leg and turpentine-induced inflammation in the left hind leg, the inflammatory tissue showed uptake of ¹⁸F-FDG but no specific uptake of ¹¹C-glycylsarcosine. This tracer could be useful for the detection of many types of cancer.
