title: CT perfusion of head and neck tumors: how we do it.
abstract: OBJECTIVE
  Our purpose is to illustrate the pathophysiologic, physical, and technical principles of MDCT perfusion imaging of head and neck tumors. The rationale for data acquisition and the interpretation of perfusion parameters will be discussed in the context of results recently published in the literature.
  
  
  CONCLUSIONS
  MDCT perfusion imaging of primary and recurrent head and neck tumors is feasible and can yield functional information that is useful for tumor grading and assessment of treatment response.
