We been asked to start writing down the dose for each CT Head/Ct Chest/Ct abd/ct lumbar. Where would you find it on the protocol page.? The CTDIvol is what they are telling us to write down. Is this correct? What does this stand for? If you could answer my question or tell me where to look for it I would greaty appreciate it. THe numbers don't really match up or make sense. When we did a spiral head it was one number and when we repeat a little of it because of motion the number was the same. That's why I don't really understand it. Where would I find the exceptable doses for things? THanks so much for all your help...Appreciate it.
