Key points

  • Consensus guidelines were developed for delineating 25 organs at risk (OARs) in the head and neck region.
  • The guidelines are intended for routine daily practice and research purposes in radiotherapy.
  • An atlas of the consensus guidelines is provided in the supplemental material, with DICOM-RT format available on request.
  • The primary goal is to reduce interobserver variability among clinicians and radiotherapy centers.

Abstract

PURPOSE: The objective of this project was to define consensus guidelines for delineating organs at risk (OARs) for head and neck radiotherapy for routine daily practice and for research purposes. METHODS: Consensus guidelines were formulated based on in-depth discussions of a panel of European, North American, Asian and Australian radiation oncologists. RESULTS: Twenty-five OARs in the head and neck region were defined with a concise description of their main anatomic boundaries. The Supplemental material provides an atlas of the consensus guidelines, projected on 1mm axial slices. The atlas can also be obtained in DICOM-RT format on request. CONCLUSION: Consensus guidelines for head and neck OAR delineation were defined, aiming to decrease interobserver variability among clinicians and radiotherapy centers.
