Abstract: High resolution cross sectional imaging dramatically improves the diagnosis and therapy of oncological patients primarily concerning the exact initial staging, differential diagnosis of recurrent tumours and therapy management. Positron emission tomography (PET) is a quantitative, functional diagnostic imaging modality using compounds labelled with positron-emitting radioisotopes to measure cell metabolism for both initial tumor staging and detection of tumour recurrence with a high diagnostic accuracy. Combined PET/CT is a unique imaging modality that permits anatomic and functional imaging on a single scan in comparison with PET alone. Nearly a decade after introduction of PET/CT, clinical combined PET/magnetic resonance imaging (PET/MRI) systems have become available commercially. PET/MRI system combines the unique features of MRI including excellent soft tissue contrast. Thus this paper portrays the usefulness of PET along with its recent advances in head and neck cancers.
