Dual isotope F-18 FDG and Tc-99m RBC imaging for lung cancer

Purpose: To produce fluorodeoxyglucose (FDG) images with markers for normal organs and large blood vessels in patients with suspected lung cancer. Methods: Dual isotope SPECT images were made using F-18 FDG- and Tc-99m-lab eled autologous red cells, Results: FDG-positive lesions are localized in r elation to major structures when they are viewed in a fused rotating three- dimensional display or in cross sections. Conclusions: Tc-99m red cell and FDG fusion imaging provides relative locat ion information for lung tumors.
