Around the world, veterinarians are turning to high-tech human medicine—especially in the field of diagnositics. Dee is a cape fur seal living at a zoo in Pretoria, South Africa. Her keeper noticed that she had a runny nose and a CT scan revealed a suspicious-looking mass, which the vet team worried was a tumor. Fortunately for Dee, another examination revealed the source of the mass was an infection caused by decay in her canines—still a serious concern for her health, but one far more treatable. Once the canines were removed, Dee was able to make a full recovery.
