The use of dedicated MR simulation and MR-guided Radiation Therapy (MR-IGRT or MRgRT) systems in Radiation Oncology is expanding at a rapid pace. This session will describe the clinically available systems for MRI in Radiation Oncology, including its use as an adjunct imaging modality, a primary treatment planning modality, MR-IGRT, and for normal tissue and tumor response assessment. MR-safe phantoms and measurement equipment will be described. Consideration will also be given to the software needs specific to the implementation of MR in radiation therapy.
In the process of incorporating MRI in radiation oncology, clinical medical physicists often face the question of how to establish an effective quality assurance program. In this session, we will provide a framework for establishing such a program based on the existing recommendations from ACR and AAPM, as well as requirements specific to radiation oncology applications of MRI. We will identify individual MRI QC tests that should be included in a comprehensive quality assurance program, provide recommendations for test frequency, and discuss tolerance limits as well as possible corrective actions.
Dedicated MR units in the radiation oncology clinic are growing in number. These devices require safety aspects that are not common to the radiation oncology environment, thus presenting the need to establish and implement MR safety practices for patients, personnel and the public that agree with national standards of practice, as well as recognize the unique challenges for patients seen and treated in the radiation oncology clinic. This session will review design of facility safety aspects, designation of MRI safety zones, components of an MR safety program, and safety experience for dedicated MR imaging in the radiation oncology clinic.
Learning Objectives:
1. Describe specific hardware and software requirements for MRI for treatment planning, simulation, guidance, and assessment in radiation oncology.
2. Select, commission, and establish appropriate quality control for MRI instrumentation used in radiation oncology applications.
3. Establish and maintain an effective MR safety program that addresses unique challenges of the radiation oncology environment.
