Thanks ozzy!

An MRA is the same as an MRI except it looks specifically at the blood vessels (they put an intravenous line into my arm and fed through contrast dye whilst i was in the machine). i went through once with my arms by my side and then went through a second time with my arms over my head.

i think it wont show anything and that i will need more test - i will push for a doppler or angiogram....why cant they just sent me for the best test the first time!....its sooo fustrating!
