The low sensitivity may in part be due to the small size of pulmonary nodules at presentation or peripheral location, in which CXR tends to be less reliable [11]. The use of CXR for detection of metastases has not been shown to improve prognosis because metastatic pulmonary nodules detectable on CXR tend to be associated with late-stage disease when it is not as amenable to treatment [18]. CT Chest Without and With IV Contrast There is no relevant literature to support the use of CT chest without and with IV contrast in the evaluation of suspected or diagnosed cancer of the oral cavity or oropharynx or hypopharynx or larynx or cancer of unknown primary of the head and neck. CT Head With IV Contrast There is no relevant literature to support the use of CT head with IV contrast in the initial staging of suspected or diagnosed cancer of the oral cavity or oropharynx or hypopharynx or larynx or cancer of unknown primary of the head and neck. 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 the initial staging of suspected or diagnosed cancer of the oral cavity or oropharynx or hypopharynx or larynx or 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 the initial staging of suspected or diagnosed cancer of the oral cavity or oropharynx or hypopharynx or larynx or 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 cancer of the oral cavity or oropharynx or hypopharynx or larynx or cancer of unknown primary of the head and neck.
