Re: thyrogen scan no hypo scan

www.genzyme.com this is the website of the company who makes

thyrogen. They talk about indications/contraindications of use, pros

and cons. One thing it says is it can be considered for use when you

have an " undetectable on-suppression Tg. "

pap thyca 2.8cm 3 pos nodes 10/00 52 mCi 4/01 mCi

> I am concerned and am looking for reassurance. My Endo is

planning on scanning me with thyrogen and not having me go hypo. This

sounds great to me but I was under the impression thyrogen was only

used as a follow-up after you have gotten 2 clean scans. I thought

they were known to not be as accurate as going hypo. I received my

intial scan following RAI in January. The scan showed residual

activity in the neck (which they believed the RAI would ablate) but I

am still getting a TG level of 2.4. Obviously there is some remaining

tissue. I realize there is no need for alarm but want to make sure I'm

not doing the wrong thing by taking thyrogen for my scan. Any feedback

would be much appreciated.
