La Tomografía por emisión de positrones (PET) en la práctica clínica oncologica

Abstract

Positron emission tomography with 18F-fluorodeoxyglucose (FDG-PET) is a diagnostic procedure which has been progressively incorporated to clinical practice in Spain during the last decade. There are several indications in which FDG-PET has demonstrated a better diagnostic accuracy when compared with conventional methods. In order to optimize the use of this new technique, it is recommendable to select those situationts where FDG-PET has shown to be clearly better than the conventional techniques, as staging of lung cancer and lymphoma; restaging of thyroid cancer, colorectal cancer, head and neck cancer, lymphoma and melanoma; localization of unknown primary site carcinomas; diagnosis of solitary pulmonary nodules; and differentiation of tumor recurrence from radionecrosis in brain tumors.
