Popis: Sodium benzoate labeled with the cyclotron produced, positron emitting radioisotope 11C ( t 1 2 = 20.4 min ) has been investigated as a potential agent for renal and tumor visualization using γ-scintigraphy. Sodium [11]benzoate was prepared by the Grignard reaction of phenylmagnesium bromide and 11C-CO2 with no carrier added. A dog bearing an osteogenic sarcoma in the head of the left femur was studied using the High Energy Gamma (HEG) rectilinear scanner at the Sloan-Kettering Institute following i.v. administration of no-carrier-added sodium [11C]benzoate. The high-contrast image of the kidneys in this dog demonstrates the potential usefulness of [11C]benzoate as a renal scanning agent. Visualization of a canine osteogenic sarcoma, in addition to a human brain tumor reported in a previous study, suggests that [11C]benzoate should be further evaluated as a tumor imaging agent.
