For detection of distant metastases inside the setting of HNC which includes medical features suggesting it might have distribute over and above the neck, the NCCN endorses PET-CT as the primary-line imaging modality, except within the location of nasopharynx cancer, the place the NCCN states that upper body CT with contrast is definitely an equal option.

Standardized uptake values are calculated by the computer software for every hypermetabolic area detected during the graphic. It offers a quantification of measurement in the lesion, since purposeful imaging does not offer a precise anatomical estimate of its extent. The CT can be utilized for that, when the lesion is also visualized in its visuals (this is not always the situation when hypermetabolic lesions are not accompanied by anatomical changes).
