title: A Delphi study to establish national cost-effectiveness research priorities for positron emission tomography.
abstract: OBJECTIVE
  This study aimed to determine the key cost-effectiveness research questions relating to positron emission tomography (PET) in the UK.
  
  
  METHODS
  A systematic literature review was conducted to establish the existing knowledge base relating to the cost-effectiveness of PET in the various conditions for which it has been proposed. A three-round postal Delphi study of relevant individuals was used to determine the key cost-effectiveness research questions relating to PET in the UK. The content and structure of the Delphi study was informed by the results of the literature review.
  
  
  RESULTS
  The most important cost-effectiveness research priorities for the National Health Service (NHS) relating to PET were in the clinical areas of lung cancer, breast cancer and the assessment of myocardial viability. Gamma camera PET using coincidence imaging was highlighted as a modality whose, clinical role needed to be determined urgently.
  
  
  CONCLUSIONS
  Underlying the cost-effectiveness research priorities which were established is the need for evidence that the use of the various PET modalities as a diagnostic technique will alter patient management as compared to existing diagnostic strategies. The findings of the project provide a contemporary overview of the potential role for PET in the NHS and will be relevant to other countries.
