I do not want to **** off another doctor pointing out a mistake, but I think I'v got another one, tho this is less critical. So I'm hoping maybe someone here can explain, so I don't have to ask her.

I am being sent for an ultrasound to look for vertebro-basilar insufficiency & subclavian steal syndrome. Because I have "hardware" in my shoulder we can't do MRI/MRA or CTA scans, the metal creates too much interference for usable pictures.

The doctor's office scheduled the ultrasound for me, and the clerk said "carotid ultrasound". I called to check on the appointment, and they said "carotid ultrasound".

This is the wrong blood vessels, right? Going to be another useless test I go through, at least as far as the problem we're trying to find?
