Transition from 3D conformal to modern modulated craniospinal radiotherapy
South African Journal of Oncology, 2022 Background: Achieving optimal tumour coverage during craniospinal irradiation (CSI) is a challenge. Whilst several critical organs are at risk of radiation-induced toxicity, if target volume structures like the cribriform plate receive less than 95% of ...
