carbon C 11 sarcosine
A radiotracer consisting of sarcosine, the N-methyl derivative of the amino acid glycine, labeled with the positron-emitting isotope carbon C 11, that can be used for tumor imaging upon positron emission tomography/computed tomography (PET/CT). Upon administration, C-11 sarcosine is taken up by and accumulates in tumor cells, thereby allowing tumor imaging with PET/CT. Sarcosine, a non-proteinogenic amino acid and oncometabolite, is elevated in certain tumor cell types. Its expression seems to correlate with increased tumor invasiveness. Check for active clinical trials using this agent. (NCI Thesaurus)
