Neck imaging after treatment for head and neck cancer can be complex to interpret. NI-RADS aids radiologists and clinical teams in risk stratification and management of surveillance imaging findings in the post-treatment setting. It can be applied to surveillance imaging of the following cancers using CT, MR, or PET:

  • Squamous cell carcinoma of the head/neck skin and aerodigestive tract (oral and sinonasal cavities, nasopharynx, oropharynx, hypopharynx, and larynx)
  • Non-squamous cell cancers of the head and neck (cutaneous, salivary gland, sinonasal, orbital tumors, and thyroid cancer)
