Abstract Background Positron emission tomography PET has a potential improvement for staging and radiation treatment planning of various tumor sites. We analyzed the use of 18F-fluorodeoxyglucose FDG -PET computed tomography CT images for staging and target volume delineation of patients with head and neck carcinoma candidates for radiotherapy. Methods Twenty-two patients candidates for primary radiotherapy who did not receive any curative surgery underwent both CT and PET CT simulation. Gross Tumor Volume GTV was contoured on CT CT-GTV PET
