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.

Ft Myers was not listed when I was looking for the MRIdian in Florida. Its listed now as coming soon on the Viewray web site. Tampa was the one I had a negative experience with. Generally, they have a good reputation but any RO that isn't willing to use the dynamic capabilities of the machine, if necessary, and has an attitude, is not someone I wanted to radiate me.
I am feeling good so far thanks.
My Lesions 4 + 3 one in TZ and one allegedly in left base don’t show in MRI or ultrasound. So this machine won’t help my case?
Matto: That’s more of a question for a RO. However, here is a link to a web page on the Viewray web site. They make theMRIdian machine. Lots of good info including the latest Mirage randomized trial study which is, I believe, a big deal.

In its indications for use paragraph it states: “ 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.”
I attended the zero prostate summit and Dr. Greenberg of Jefferson Health System in Philadelphia indicated that the clinical trial ended due to the high success of the treatment.
Is this used on patients with those who have Metastic prostate Cancer and spread only to the bones ?
I am not sure of the extent of your metastasis or the extent of its use with metastatic issues but if you fall into the category of oligometastatic where it is limited in extent, and the number of metastatic lesions is small, it may be worth talking to an RO about the MRIdian machine. My brothers recent prostate cancer had metastasized and was treated with the machine at NY Presbyterian/Cornell Weill in NYC. They also gave him hormone therapy. Let me know if you need the RO dr’s name. Here is the link to locations of the MRIdian machine:

I have a consult with Dr. Kishan on the 23rd. I’m unfavorable IR, Gl 7(4+3), 63 yrs old, athletic & healthy. Except, of course, for the PCa…Thanks to bens1 posts, I looked more closely at the viewray vs truebeam Sbrt. How are you doing? SE’s? Thanks for any info.
So far all is good. No side effects to speak of and really happy with treatment and Dr. Kishan’s communication and monitoring. Still undecided on the length of ADT following treatment and am getting a variety of opinions about that. Once ADT has ended, the PSA measurements will be more reliable. Right now, cautiously optimistic. Good luck to you.
@bl2023 do you live in California? I am finding some hurdles to Dr Kishan as I live out of state.
I do. It’s not cheap because I’m a Kaiser patient so it’s out of pocket.
