Noncontrast CT chest may be considered as an alternative and is part of routine clinical practice, although there is paucity of relevant supportive literature evaluating the use of CT chest without IV contrast. CT Head With IV Contrast There is no relevant literature to support the use of CT of the head with IV contrast in the initial staging of suspected or diagnosed cancer of the paranasal sinuses or nasal cavity. CT head may provide sufficient coverage for the anatomic evaluation of the primary tumor site in the sinonasal cavity; however, inclusion of the neck is recommended 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 of the head without and with IV contrast in the initial staging of suspected or diagnosed cancer of the paranasal sinuses or nasal cavity. CT Head Without IV Contrast There is no relevant literature to support the use of CT of the head without IV contrast in the initial staging of suspected or diagnosed cancer of the paranasal sinuses or nasal cavity. 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 cancer of the paranasal sinuses or nasal cavity. CT maxillofacial may be complementary in the anatomic evaluation of the primary site, in particular 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 cancer of the paranasal sinuses or nasal cavity.
