What will a veterinarian be looking for in my cat’s diagnostic imaging?

Specifically for ultrasounds, if we're looking at the abdomen, we're often looking at the internal organs themselves, and if we're looking for a possible mass or a problem with the function of the organ. We use it a lot for the bladder to look for why a cat may be urinating inappropriately. We may also use it to collect samples. We will use ultrasound if we're trying to collect urine. X-rays would be better for orthopedic reasons or even just looking at the whole cat. We could look at the chest and the abdomen and zero in if we're not sure where that problem is.
