Important Safety Information
Indications for Use (IFU): The MRIdian Linac system, with magnetic resonance imaging capabilities, is intended to provide stereotactic radiosurgery and precision radiotherapy for lesions, tumors, and conditions anywhere in the body where radiation treatment is indicated. The MRIdian Linac System is not appropriate for all patients, including those who are not candidates for magnetic resonance imaging.
Important Safety Information (ISI): Radiation treatments may cause side effects that can vary depending on the part of the body being treated. The most frequent ones are typically temporary and may include, but are not limited to, irritation to the respiratory, digestive, urinary or reproductive systems; fatigue; nausea; skin irritation; and hair loss. In some patients, side effects can be severe. Treatment sessions may vary in complexity and duration.
Radiation treatment is not appropriate for all cancers. You should discuss the potential for side effects and their severity as well as the benefits of radiation and magnetic resonance imaging with your doctor to make sure radiation treatment is right for you.

Results of treatment presented in the videos and information on this webpage are not indicative of typical or future results.
Discuss treatment options with your doctor, including the risks and benefits of the entire course of treatment specific to your individual needs. MRIdian Linac systems are only available at appropriately equipped facilities with specially trained physicians.

James Good, MD, Clinical Director of SBRT, GenesisCare Oxford
Patient: 54-yo female; ER(+) HER2(-) primary breast tumor, previously Tx w/ lumpectomy and post-op RT; presented with 3 liver mets on FDG PET and MRI
Treatment Options: Surgery too risky, not able to get complete disease; standard radiation not an option
Challenge: Lesion location: Very susceptible to motion; requires complex setup w/ abdominal compression and fiducials; movement up to 2 cm would lead to large ITV and irradiating healthy tissue; conventional Linac would compromise PTV dose to meet OAR constraints; likely reduce overall dose to avoid exceeding mean liver tolerance
MRIdian: 35 Gy in 5 Fx, keeping OARs in tolerance; daily adaptation for ablative dose to tumor while keeping critical structures within tolerance; real-time automated beam gating with patient directed breath-hold allowed accurate dose delivery
Outcome: Able to deliver 50 Gy to three lesions. Three-month follow-up shows clear ablation zone and elimination of tumor

“MRIdian may radically change pediatric radiotherapy indications.”
Enis Özyar, MD, Professor of Radiation Oncology, Acibadem Maslak Hospital
Patient: 15-mo with very rare pediatric metastatic liver tumor and huge celiac lymph node compressing biliary system
Treatment Options: RT not typically offered due to risk to anatomy—small structure size and motion; patient not a candidate for chemo
Challenge: Understanding efficacy and safety of shorter hypofractionation schemes is critical to improving pediatric palliative care. In this pediatric case, we aimed to deliver treatment within a short period of time with minimal toxicity. Technically, it was not possible to ideally treat this mass with other radiotherapy systems as we needed fiducial markers and adaptive approach
MRIdian: 25 Gy in 5 Fx, every other day
Outcome: ~40% reduction in size over course of Tx making on-table adaptive re-planning essential; would have never known tumor was shrinking if treated with x-ray-guided system
