Neurocognition and mean radiotherapy dose to vulnerable brain structures: new organs at risk?

Radiation Oncology, 2023
Background Children with brain tumors are at high risk of neurocognitive decline after radiotherapy (RT). However, there is a lack of studies on how RT doses to organs at risk (OARs) impacts neurocognition.
