Okay, bear with me, please. A couple of techs are wrangling about proper angles while doing renal Doppler: One says that you can't go below 45 degrees, even if the actual angle relative to vessel wall is zero degrees. The other says it's better to use the actual angle (assuming it's not possible to obtain a 50-60 degree angle).
I most certainly know what I think, but a few opinions from heavyweights would be helpful. (These young folks think I'm half senile and don't listen to me.)
