MRIdian Viewray Experience

Making a decision related to which radiation machine one uses seems to be something that does not get a lot of discussion by urologists and radiation oncologists in terms of the differences, other than their success with the machine they use. I chose the MRIdian Viewray. There are multiple choices with different capability and toxicity risks.

I had my first treatment, out of 5, on January 31. I had spaceoar gel inserted. The machine is both a radiation and MRI built into one unit. They can see healthy tissue and the cancer in real time and adjust accordingly using the machines dynamic mapping capability, if necessary. They used 2 mm margins based on a recent randomized trial called Mirage. The machine turns off automatically if your internals move and the radiation goes outside the mapped out area. No pain or real side effects after the first treatment. Second treatment is on Friday. My prostate cancer is contained within the prostate and I am almost 70 with Gleason 3+4 on one core and 3+3 on another. Psa was 10.2.
