Cuts like a GammaKnife.

What’s better at sparing the hippocampus than hippocampal-sparing whole brain radiation? Stereotactic radiosurgery (SRS). That is if you’re up for treating well over 10 brain mets, and no one’s saying that you’re not. Here, a GammaKnife-based technique was used to treat patients with 10+ brain mets with >85-90% reductions in the dose to the hippocampi and normal brain. | Nguyen, Int J Radiat Oncol Biol Phys 2019
