IFRT offers viable alternative to WBRT Whole brain radiation is traditionally used when someone has a metastatic brain tumor. This article shows a small study which shows a limited field may be just as useful, with less side effects. This is not controlled trial where they randomized 1/2 of the patients to involved field radiation and compared them to the half who got whole brain, so although it looks encouraging, so I would love to see others repeat it to make sure it is valid. But it is something to consider.
