The use of F-18-FDG with positron emission tomography (PET) is a well established method in oncology investigation on clinical practice. With the development of dual-head gamma-cameras equipped with coincidence circuit and local production of that tracer, metabolic studies with this glucose analog became possible in our country. The aim of this work is show the first results obtained with that methodology. We studied 18 patients with different tumors such as colorectal , breast , ovarian , thyroid, head and neck and gastric carcinomas, melanoma and soft tissue sarcomas. All of them had clinical suspicions of tumor recurrence or residual tumor presence. Studies were performed in a gamma-camera equipped with coincidence circuit (Elscint –VariCam), 45 minutes after I.V. administration of 5 a 10 mCi (185 a 370 MBq) of F-18-FDG . Abnormal studies were found in 9 out 18 patients. F-18-FDG studies disclosed occult disease and helped the oncological evaluation in cases where conventional diagnostic images failed to show any abnormality.
