Hope somebody's awake... test dye question

[Guest guest]

My husband has to take a CAT scan with radioactive iodine tomorrow.

(At least, I think that's what the doc said. I was in a bit of a panic.)

I was planning to give him a good, stiff dose of iodine before the

test, to reduce the risk of his thyroid absorbing the radioactive

crap. (The potassium iodide does protect from radioactivity, right?)

I have had him on iodine for a while, so I don't expect detox

problems, & hopefully the months on a moderate dose of iodine will

already afford some protection. But then it occurred to me to wonder,

would that screw up the test? Anybody know anything about this?
