Thanks. Im on Medicare so 20% of Doppler's on me. MRV - Doppler is 1st step I told my Dr. If it shows reason to go further, MRV follows. Yes I wish I could go straight to MRV, especially since I do what I do withh MR's as you see in my album. I heard the Doppler is able to go home with me on cd like mr, ct pet so yes I'll post pictures if possible
