The Challenges of Using MRI During Radiotherapy

In this article we aim to introduce the main considerations in integrating magnetic resonance imaging (MRI) into the radiotherapy workflow. We will cover the use of MRI for improved delineation, considerations regarding MRI-only workflows, and the potential of functional imaging techniques. The challenges of implementing each of these will be discussed to ensure safe usage in radiotherapy. (C) 2018 The Royal College of Radiologists. Published by Elsevier Ltd. All rights reserved.
