I had 5 hypo fractional treatments with the Mridian built in MRI radiation machine (vs fused images) so everything treated was in real time and the amount of healthy tissue exposed to radiation was less than other radiation machines. If you have ever had an MRI, that was what the experience was close to. I also had spaceoar before treatment. Some urination restriction thereafter but for me, it did not last long and I took Flomax for about a month afterwards.
