Yes they do. Type IMRT in the search engine once you are on their site. It appears that they just recently got it.
If you are Seattle can you go to "The Fred Hutchinson Cancer Research Center"? They are an NCCN/NCI hospital See
http://www.nccn.org/profiles/hutchinson.htm Virgian Mason might be a great hospital - I don't know anything about them. Their site and clinical trials looked impressive.
The 17 hospitals that comprise the NCCN memberships are at the cutting edge of cancer treatment and research and have the most expertise.
I deliberately sought out an NCCN hospital for comprehensive cancer care. I wanted to take my best shot at this disease and my personal opinion is that comprehensive cancer centers offer the most hope.
