Oncologic diagnosis with 2-[fluorine-18]fluoro-2-deoxy-D-glucose imaging: dual-head coincidence gamma camera versus positron emission tomographic scanner.

Abstract

These preliminary findings indicate FDG imaging with a modified dual-detector gamma camera operating in coincidence mode can depict many of the lesions depicted with a PET scanner, particularly in the lungs. Sensitivity for lesions detected at dedicated FDG PET was poor in the abdomen and in all locations outside the lungs for tumor deposits generally less than 1.5 cm in short-axis diameter.
