CT Neck Without and With IV Contrast There is no relevant literature to support the use of CT neck without and with IV contrast in the initial staging of suspected or diagnosed cancer of the paranasal sinuses or nasal cavity. CT Neck Without IV Contrast There is no relevant literature to support the use of CT neck without IV contrast in the initial staging of suspected or diagnosed cancer of the paranasal sinuses or nasal cavity. CT neck without IV contrast would not provide Assessment of Head and Neck Cancer sufficient evaluation of the soft tissue extent of disease but may be complementary in the anatomic evaluation of the primary site in particular for the evaluation of osseous erosion. CTA Neck With IV Contrast There is no relevant literature to support the use of CTA with IV contrast of the head and neck in the initial staging of suspected or diagnosed cancer of the paranasal sinuses or nasal cavity. CTA of the neck can be used to identify patients at high risk of bleeding in the instance of locally advanced disease encroaching on the carotid arteries [41]. FDG-PET/CT Skull Base to Mid-Thigh FDG-PET/CT allows for the detection and localization of primary tumor site and identification of regional nodal disease and distant metastases. FDG-PET/CT alone is not considered sufficient in initial staging because it may not provide detailed anatomic delineation of the primary site or detection of upstaging features needed for correct staging, surgical, and treatment planning [100]. Furthermore, previous authors have suggested that PET/CT may in fact overestimate the extension of the tumor [101]. However, FDG-PET/CT is recommended by the National Comprehensive Cancer Network as an adjunct in the workup of stage III and IV cancers [42]. FDG-PET/CT has shown increased sensitivity for detection of regional nodal disease, distant metastasis, and synchronous tumors over radiography and cross-sectional imaging with CT and MRI [42].
