How to simplify management of complex uroliths

September 1st 2003This month, we begin a series covering a particularly relevant topic in veterinary law, yet one that is widely overlooked both by lawyers when they are counseling veterinarians and veterinarians as they seek out legal advice.

We use it to "rule out" numerous diseases. Unfortunately, we have known that it takes a marked change in the electronic density of the material to be seen radiographically. Some estimates indicate that in bone, radiographic density must change by 30-50 percent (either increase or decrease) in order to be visible on a standard radiograph. Therefore, numerous diseases can be present and escape the detection limit of a radiographic change. We must remember
