Today, MR has even more to offer for radiation treatment planning. Innovative MR-only simulation by Philips helps you rely on MR as a primary imaging modality for prostate cancer treatment planning. Available as a plug-in extension to Ingenia MR-RT, MR-only simulation allows you to adopt a single-modality imaging approach that provides excellent soft-tissue contrast you trust for target delineation - plus density information for dose calculations. Fast scanning protocols and embedded post-processing steps generate MRCAT (MR for Calculating ATtenuation) images on the MR console in just a few minutes with the density information you’d expect from CT.
Dr. Uulke van der Heide describes MR’s changing role in radiotherapy and a recent collaboration with Philips to bring MR-only simulation for RT planning from the lab to clinic. The Philips Ingenia MR-RT platform now supports MR-only simulation for planning the treatment of prostate cancer patients. Prof. Dr. van der Heide is a medical physicist at the Netherlands Cancer Institute in Amsterdam.
A combined MR-CT approach can benefit radiation treatment planning. In most clinical workflows, MRI-based information on tissue characterization and tumor delineation is registered to a primary CT dataset. This provides the electron density information as input for dose calculations. Yet this method can also put pressure on workflows, patients, and costs. CTMR image registration also introduces uncertainties. Errors in the alignment of MR and CT images series in the treatment preparation stage propagate as a systematic geometric error following the patient throughout the entire treatment period.
An MR-only simulation workflow can eliminate technical, worfklow and economic challenges related to the MR-CT multimodality imaging workflow for specific tumor types and help you adopt MR for your treatment planning.
Philips MR-only simulation provides a fast and automated approach to obtain excellent soft-tissue contrast and robust 3D density maps in one MR imaging session.

To successfully bring MR-only simulation into your clinical routine, we recognize the need to look beyond MR imaging – and also address steps such as patient marking, position verification, and quality assurance. We can help you successfully adopt this new simulation paradigm with our workflow descriptions and tailored training support for radiation oncology professionals.
