Examining the kidneys using Colour & Power Doppler

If you have been performing any kind of small animal abdominal scanning, you will no doubt be familiar with kidneys. Even if you specialise purely in canine or feline pregnancy scanning, you will certainly have bumped into one or two in your travels.
