Intensity-modulated radiation therapy or volumetric-modulated arc therapy to reduce alopecia, xerostomia, and otitis after whole brain radiation therapy for brain metastases: a planning analysis

Objective The purpose of this study is to investigate the potential for reducing dose to the scalp, parotid glands, and external auditory canals using intensity-modulated radiation therapy (IMRT) or volumetrically modulated arc therapy (VMAT) to deliver whole brain radiation therapy (WBRT).
