Jen,

I had 2 positive nodes and they didn't even bother with the CT simulation, they used x-ray to set me up. This was at MSKCC. The fact that you are at a Cancer Center and, additionally, they seemed to have the appropriate answer about the IMRT should make you more comfortable. The CT. simulation would make me think that they will be doing 3D, which is the middle of the technological scale. Please be careful. Do not to let the fear of side effects cloud you judgment here. I had full blown radiation to both sides and the center of my neck, and I still have enough saliva so I don't need a bottle of water attached to my hand. You need to place some trust in your doctors and you want to be aggressive. You do not want to travel this road again, it sucks!

Good luck,
Glenn
