Abstract

<abstract xml:lang="en" abstract-type="author" id="ab005"> <title id="st275">Abstract</title> <sec> <title id="st235">Purpose</title> <p id="sp0005">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.</p> </sec> <sec> <title id="st240">Methods</title> <p id="sp0010">Anatomical descriptions and neuroimaging atlases of the brain were studied. The dosimetric constraints used in literature were reviewed.</p> </sec> <sec> <title id="st245">Results</title> <p id="sp0015">A Computed Tomography and Magnetic Resonance Imaging based detailed atlas was developed jointly by radiation oncologists, a neuroradiologist and a neurosurgeon.</p> <p id="sp0020">For each organ brief anatomical notion, main radiological reference points and useful considerations are provided.</p> <p id="sp0025">Recommended dose-constraints both for adult and pediatric patients were also provided.</p> </sec> <sec> <title id="st250">Conclusions</title> <p id="sp0030">This report provides guidelines for OARs delineation and their dose-constraints for the treatment planning of patients with brain tumors.</p> </sec> </abstract>
