This was done in both a lying down and sitting position. I also had an MRV and a CT done, but they didn't show anything the ultrasound couldn't pick up. Wish I'd saved myself the time, money, and radiation!

I also had the ultrasound done where they attach probes to the fingertips and had me move my arms above my head and out to the side while sitting up. This was strictly to test arterial compression.
