Re: Dr. Sandy MacDonald's paper on doppler ultrasound techni

Well, there seems to be enough disagreement here to go around. I hope doctors in my country, who are qualified to make diagnoses like this, are free both to do so, and to use or recommend whatever works, if they can fix it. I hope people with "MS" in this country are able to rely on doctors with proven track records to make determinations, and to act on them.
BTW, MRI can size veins very accurately, as Dr. Haacke has been trying to tell people. Doppler ultrasound (or IVUS) can guide measurement. Much can be measured from an MRI, depending on resolution. Whether one is available, or gets used, can't be predetermined.
If some other kind of impediment is already obvious by venography, CAT scan, or any other way, the presence of a web or septum may or may not affect treatment. It is up to the IR or vascular surgeon, or neurosurgeon or other specialist I may have asked for, or been referred to, to decide on and know how to use whatever armament, regardless of what precious metal it is associated with.
I rely on them to know the appropriateness of MRIs, IVUS, venography, Doppler or plethysmography. I think having the right information is important when choosing my doctor, and discussing my treatment.
The best practices evolve and replace the old best practices. They are a snapshot only, and may last for one procedure or many.
I am still asking questions. I don't want to claim any agenda, or to know any of the answers for anyone but myself.
Let us agree to disagree. I have said what I think.
