Purpose: Accurate organs at risk definition is essential for radiation treatment of brain tumors. The aim of this study is to provide a stepwise and simplified contouring guide to delineate the OARs in the brain as it would be done in the everyday practice of planning radiotherapy for brain cancer treatment.
Methods: Anatomical descriptions and neuroimaging atlases of the brain were studied. The dosimetric
constraints used in literature were reviewed.
Results: A Computed Tomography and Magnetic Resonance Imaging based detailed atlas was developed jointly by radiation oncologists, a neuroradiologist and a neurosurgeon. For each organ brief anatomical notion, main radiological reference points and useful considerations are provided.
Recommended dose-constraints both for adult and pediatric patients were also provided.
Conclusions: This report provides guidelines for OARs delineation and their dose-constraints for the treatment planning of patients with brain tumors.
