In my case, it showed plaque on the left
carotid artery and no plaque, but narrowing,
on the right - it is tortuous/looped which can be indicative of FMD.
It's important to find a cardiologist that knows about FMD, as my first set of dr's where I live, did not even know what I was talking about. I had to go to NYC to find a specialist in this area.
Good luck!
