Relationship between the uptake of 18 F-borono-L-phenylalanine and L-[methyl- 11 C] methionine in head and neck tumors and normal organs

Background and purpose The purpose of this study was to determine the distribution of 4-borono-2-18F-fluoro-phenylalanine (18F-BPA) and L-[methyl-11C] methionine (11C-Met) in normal organs and tumors and to evaluate the usefulness of 11C-Met/PET in screening potential candidates for boron neutron capture therapy (BNCT).
