Imaging and PET-CT of head and neck cancers (in French)

PET/CT is essential before extensive and mutilating surgery to exclude metastases; is mandatory to assess the efficiency of concurrent cytoreductive chemoradiotherapy for organ preservation treatment; is required for surgical follow-up to detect local recurrences, metastases, or metachronous lesions; is useful to identify the primary lesion in patients with metastases from unknown primary site; and is useful to assess metabolic tumoral volumes, especially nodes, before radiotherapy.
