ISMRM22 - Quantitative MRI for Radiotherapy: Bridging Communities of ISMRM-ESMRMB & ESTRO

Joint Annual Meeting ISMRM-ESMRMB & ISMRT 31st Annual Meeting • 07-12 May 2022 • London, UK

Quantitative MRI for Radiotherapy: Bridging Communities of ISMRM-ESMRMB & ESTRO

Member-Initiated Symposium

Wednesday, 11 May 2022

ICC Capital Hall 2

16:45 - 18:45

Session Number: MIS-10

Petra van Houdt, and Oliver Gurney-Champion.

Overview
Quantitative imaging biomarkers (QIBs) derived from MRI techniques, like diffusion-weighted imaging and dynamic contrast-enhanced MRI, have the potential to personalize radiotherapy treatment. As radiotherapy is often delivered in multiple fractions over the course of weeks, QIBs can be utilized in various ways, including the prediction of outcome to different radiation dose based on pretreatment images, adaptation of treatment plan during treatment, and response assessment after completion of radiotherapy. Furthermore, they can be used to guide contouring for treatment planning as they can show good tumour visibility. With the recent introduction of an integrated MRI and radiotherapy treatment system, the interest in QIBs for radiotherapy is growing.

However, introducing QIBs is not trivial and a lot of steps need to be taken before QIBs can be used clinically to personalize radiotherapy treatments, both from a clinical and technical perspective. Collaboration between the MRI and radiotherapy communities is needed to make this happen.

In 2022 the annual meetings of the ISMRM-ESMRMB and ESTRO (European Society for radiotherapy and oncology) are organized at the same time. With this symposium we would like to make use of this occasion and bring both communities together. We invited speakers from ISMRM-ESMRMB and ESTRO to discuss the opportunities and challenges of quantitative MRI for radiotherapy.

Target Audience
MRI researchers (both clinical and technical) with interest in quantitative MRI and/or radiotherapy
