Metabolic response on posttreatment FDG-PET/CT has been shown to be an independent prognostic indicator conferring improved survival [149]. FDG-PET/CT has a high sensitivity and accuracy in detecting distant metastases, including osseous and pulmonary metastases [82,87,88], the most common sites for distant metastatic disease in NPC. 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 response assessment and evaluation of recurrence following treatment of cancer of the head and neck with FDG-PET/MR performing similarly to FDG/PET CT [137,138]. Assessment of Head and Neck Cancer MRA Neck With IV Contrast There is no relevant literature to support the use of MRA neck with IV contrast in the follow-up imaging or evaluation of suspected or known recurrence of treated cancer of the nasopharynx or EBV-associated 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 neck without and with IV contrast in the follow-up imaging or evaluation of suspected or known recurrence of treated cancer of the nasopharynx or EBV-associated 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 neck without IV contrast in the follow-up imaging or evaluation of suspected or known recurrence of treated cancer of the nasopharynx or EBV-associated cancer of unknown primary of the head and neck. MRI Head With IV Contrast There is no relevant literature to support the use of MRI head with IV contrast in follow-up imaging or evaluation of suspected or known recurrence of treated cancer of the nasopharynx or EBV-associated unknown primary of the head and neck.
