I've had Hasimoto's Thyroiditis for over 5 years. My doctor has sent me to get a I123 scan twice. The first time, the tech didn't finish, he said he couldn't see anything. I was off my med for 4 weeks. Recently we did it again, a different location and they told me to say off for 2 weeks only... they finished it but it came back saying the same. They couldn't see it.
My question is... any ideas on why they can't see it?
Doc is sending me now for another type of test, something involving iv's.. oh fun!
