Dogma,

Thanks, I am not weary of close spaces, but when your dizzy and head is already pounding that sound even with ear plugs and muffs is very loud and disturbing. Under regular circumstances I agree it is no big deal. But in my and I would have to generalize most of our conditions, it is very loud and difficult.

I would think the noise is the only part of the test that would be hard if you are not afraid of the close space or IV. At least it was the case with me. But I do agree you can work with the doctor in advance for a sedative as long as you have a ride if there are issues.

Laura. :)
