Treatment planningConsensus opinion on MRI simulation for external beam radiation treatment planning

AimTo determine the levels at which consensus could be reached regarding general and site-specific principles of MRI simulation for offline MRI-aided external beam radiation treatment planning.MethodsA process inspired by the Delphi method was employed to determine levels of consensus using a series of questionnaires interspersed with controlled opinion feedback.ResultsIn general, full consensus was reached regarding general principles of MRI simulation. However, the level of consensus decreased when site-specific principles of MRI simulation were considered.ConclusionsThese results indicate variability in MRI simulation approaches that are largely explained by the use of MRI in combination with CT.
