I recently just looked at the GE.  Was impressed.

        Let me say upfront that I do not sell ultrasound equipment, I have
no
        financial interest in ultrasound equipment, and I do not work
commercially.
        I encourage all to evaluate the equipment for yourselves because I
have not
        looked at every piece of ultrasound equipment out there - at least
not
        currently. I can only comment on what I am using or have looked at
very
        recently for AAAstent assessment and have found that the
Acuson/Sequoia and
        ATL/HD5000 have demonstrated what I need to see and the XP's do not.
I hope
        the rest of you will lets us know what is working and what is not.

        Bonnie,    You speak specifically of "your" imager being more then
adequate
        to
        image deep abdominals for endo stent follow ups. Tell me a secret,
what
        imager
        are you using at Stanford to follow these up. We are doing multiples
here
        ie.
        4-6 per month and have no follow up capabilities at this time.
Currently
        using
        ATL's 3000's, 3500's, and HP5500. What do you consider an adequate
machine
        set
        up correctly to see what "we" need to see???   Thanks,    Ric
