| A system that uses 3 X-rays from diffenrent angles to allow more infomation to be read and analyzed, I think that offers more objectivity and accuracy. That is the case of the PennHIP mehtod. As far as OFA ratings is concerned, there has been so many wrongful readings that one truly wonders what the actual status is, in any given case... Obviously, the Orthophedic Foundation Animal will not accept such sensible reasonings and scientific documented data... After all, there is money to be made, and OFA don't want to loose the tight-grip they have stablished in the dog breeding business. |
