agreed but internal valadation (OR) agrees.  Poor at  best

Response
According to the criteria of Strandnesss any diastole less than 100 or 140 which ever
criteria  you use is less than 80-99%

Don, I have a GE and from now on.. ICA stenoses are measured
 
1. with color and angle correction to the wall.
2. B-flow with angle correction to the wall
3. Steer the color and B-flow box to bring out the highest flow..
4. 60 degrees of less...
 
I walk threw the entire stenosis and look at the jet in color and b-flow
I record a cini loop of the stenosis w B-flow
 
I take the higher of the 2.
 
you can always make something to lower than higher. Also with heavy breathing you
know as well as I the sample gate in moving in and out of the center of the jet...
Up and down,,, up and down.. got to get it in sync with the common carotid velocity
for ratio. If you take too long to get the ICA flow, go back and do the CCA within a few mins.
of both velocities.
 
What category do you use for 80-99% stenosis..???
 
350/140 minimum  with a 3.5 to 5 ratio?
 
Thanks Don, and keep swinging that transducer..

The box angled had a 54 angle corrections only (not that different)
The box straight had an angle of 60 degrees, vessel was at a 60 also.
same jet area in both samplings.
What a difference yeh?--

You're saying that the spectral-Doppler angle was the same as the first
reading, just the color-box angle changed?

Don,
Here's something interesting-- I just did a patient with a 80-90%
He was large, breathing movements, ect.
Diving vessel. There was no way I was going to get a 60 on this guy--
So I got the "correct " velocity and then just for grins and giggles
Turned the color box straight up and down and got a velocity at 60--
Guess what-- my 404/110 went to 286/80!
 I think it is the color box with the 60 angle.
Oh by the way-- the true angle of the flow was 54 degrees for the
stenosis
With the color box angled.
Just thought that was interesting as I just had the patient on the table
after reading a few comments.
Lisa
