FDG PET imaging of paragangliomas of the neck: comparison with MIBG SPET

Abstract

Two patients with cervical paragangliomas underwent positron emission tomography (PET) with 2-[ 18 F]-fluoro-2-deoxy-D-glucose (FDG). There was marked tumor uptake and retention of FDG. Adjacent salivary gland accumulation of FDG was minimal, though quite prominent with meta -iodobenzylguanidine. FDG PET offers another potentially useful approach to functional imaging of these uncommon tumors, independent of the presence of specific amine uptake mechanisms or cell surface receptors required by other scintigraphic techniques.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/46837/1/259_2004_Article_BF00801625.pd
