FDG-PET/CT is considered standard of care for the evaluation of metastatic cervical adenopathy with no primary evident on clinical examination or other imaging modalities [17]. FDG-PET/CT has been demonstrated to be superior in detecting the primary site (69%) at the time of diagnosis versus 15% on CECT alone and 41% when using the combination of CECT and MRI [17]. FDG-PET/CT has been demonstrated to have a higher diagnostic accuracy than MRI and CT for the detection of small tumors [50,51]. FDG-PET/MRI Skull Base to Mid-Thigh FDG-PET/MRI is a new imaging modality with a growing body of evidence demonstrating the feasibility of use for routine clinical imaging, including the initial staging of head and neck tumors, with FDG-PET/MRI performing similar to FDG-PET/CT [42,44,52-57]. One study found that FDG-PET/MRI outperforms FDG-PET/CT in the diagnosis of primary site in the evaluation of unknown primary [58]. MRA Neck With IV Contrast There is no relevant literature to support the use of MR angiography (MRA) with IV contrast of the neck 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. MRA Neck Without and With IV Contrast There is no relevant literature to support the use of MRA of the neck 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. MRA Neck Without IV Contrast There is no relevant literature to support the use of MRA of the neck 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.
