CT Head With IV Contrast There is no relevant literature to support the use of CT head with IV contrast in treated cancer of nasopharynx or EBV-associated cancer of unknown primary of the head and neck. Although CT head may be able to delineate skull base and intracranial involvement, inclusion of the neck is useful to evaluate for cervical adenopathy for staging purposes. CT Head Without and With IV Contrast There is no relevant literature to support the use of CT head without and with IV contrast in treated cancer of the nasopharynx or EBV-associated cancer of unknown primary of the head and neck. CT Head Without IV Contrast There is no relevant literature to support the use of CT head without IV contrast in treated cancer of the nasopharynx or EBV-associated cancer of unknown primary of the head and neck. CT Maxillofacial With IV Contrast There is no relevant literature to support the use of CT maxillofacial with IV contrast in the initial staging of suspected or diagnosed NPC or EBV-associated cancer of unknown primary of the head and neck. CT maxillofacial with IV contrast may provide sufficient evaluation of the primary site and can be particularly helpful for the evaluation of osseous erosion. However, CT maxillofacial will typically not include evaluation of the neck and would therefore be inadequate for the staging of regional lymphadenopathy when performed alone and may best be used in combination with MRI or FDG-PET/CT. CT Maxillofacial Without and With IV Contrast There is no relevant literature to support the use of CT maxillofacial without and with IV contrast in the initial staging of suspected or diagnosed nasopharynx cancer or EBV-associated cancer of unknown primary of the head and neck. CT Maxillofacial Without IV Contrast There is no relevant literature to support the use of CT maxillofacial without IV contrast in the initial staging of suspected or diagnosed NPC or EBV-associated cancer of unknown primary of the head and neck.
