Flow quantification is the charts and graphs with the flow information? I had that.
Verdict is still out on if it was helpful to me or not. It showed the two jugular stenoses that were found and treated in the venogram, but they would have been found regardless. The flow information itself was not of interest to anyone but me. It also showed what looks to me like a large obstruction in the lower area of the azygous (not the arch) but upon venogram Dr. Sclafani did not find anything there; however, I'll be having a repeat venogram with ivus which was not previously used in my azygous. If upon ivus he finds such an obstruction, the MRV will have been helpful. Otherwise, it's main use was to give me an image to hold onto while I waited for my turn for my procedure.
It would be nice to have a before-and-after MRV, particularly for anyone treated in the azygous, but it still see is unproven if the MRVs are reliably showing what's there anyway.
