title: [Usefulness of the new classification for regional extension on CT of head and neck cancer].
abstract: OBJECTIVE
  To present the usefulness of the new classification of neck nodes based in commuted tomography (CT).
  
  
  METHODS
  We present several illustrative images showing neck nodes in each of the new levels (Ia, Ib, IIa, IIb, III, IV, Va, Vb, and VI) as an adjunct to nodal classifications.
  
  
  CONCLUSIONS
  An imaging-based classification for the cervical nodes allows to know much better their distribution along the neck, helping to find correlation between clinical, radiological and surgical findings.
