Following a few hrs, the affected person is placed into the PET–CT system, ordinarily lying within a supine posture While using the arms resting at the edges, or brought alongside one another over the head, depending on the main region of curiosity (ROI).
For detection of distant metastases while in the environment of HNC which has medical functions suggesting it might have distribute beyond the neck, the NCCN suggests PET-CT as the initial-line imaging modality, except from the environment of nasopharynx cancer, exactly where the NCCN says that chest CT with contrast is an equivalent choice.

It offers a quantification of sizing of the lesion, because practical imaging would not give a specific anatomical estimate of its extent. The CT can be employed for that, in the event the lesion can be visualized in its images (this isn't constantly the situation when hypermetabolic lesions are not accompanied by anatomical changes).
