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.

“ViewRay’s MRIdian is our first choice treatment for partial breast irradiation because we can actually see the treatment live and reduce certain errors that are known to happen with CT-based treatment. We’re no longer limited to the ‘peek and shoot’ mentality of other treatments.”

Noteworthy Clinical Findings
Siteman Cancer Center at Barnes-Jewish Hospital and Washington University School of Medicine in St. Louis, MO recently completed a prospective phase I/II trial of 50 patients. It showed that single-fraction HG-PBI was well tolerated and resulted in few adverse events.
Study Specifics
Patients received postoperative single-fraction 20 Gy dose to the cavity surface while simultaneously prescribing 5 Gy to a PTV defined as the surgical bed plus a 1 cm margin
Key Findings
- No grade 3-5 toxicities observed
- 100% excellent to good cosmesis reported by both patients and treating physicians
- Patient-reported quality of life did not decrease after treatment
- Excellent early local, regional, and distant control rates
This study, Kennedy et al. (2020), was published in the February issue of the International Journal of Radiation Oncology * Biology * Physics.
