To those of you who went to Port Perry Imaging to have an ultrasound, can you give me an idea of their accuracy?  I'm going this week and know that the IR has trained under Dr. Sandy Mccdonald.  I'm just curious as to if anyone went and got a false negative or false positive?  I'm also curious as to if they give your results immediately or how long it takes to get them?  Finally, to those who have tested positive, do the results state that you have CCSVI or does it go into detail with regards to how many blockages and where?  I'm decided on going regardless, but just wanted to know what to expect up front.  Thanks....Steve.
