Diagnostic Imaging: Through the Eyes of a Vet
Use these X-rays and ultrasounds to look inside a cat, dog, or horse. Diagnostic images help veterinary teams diagnose problems and treat animals in their care.

Dog Case Study #1 with x-rays and photos — external fixator
One Brave Pup
he CSU Veterinary Teaching Hospital saw this patient when he fractured the tibia and fibula bones of his left hind leg. The veterinary team repaired his injury using a device called an external fixator.

Veterinarians used two X-ray (radiograph) views (cranial, lateral) to assess placement of the device and the fracture immediately after repair. Can you see the fracture in each radiograph?

Veterinarians use an external fixature to stabilize the fractured bones and allow them to heal while also giving the animal the ability to walk during the healing process.

Compare the Radiographs
In addition to taking radiographs to help diagnose bone fractures, veterinary teams use radiographs during the healing process to make sure the bone is healing properly.
Dog Case Study #2 with X-rays and Photos – Dog Pregnancy
Pregnancy Radiographs (X-Rays)
Radiographs can be used at later stages of pregnancy to see how far along a pregnancy is, as well as determine the number and location of the puppies. What do you see in this close-up image?

Count the Puppies
How many puppies can you find? What other bones and features do you notice?

During birth, puppies have to pass through the birth canal, which is formed by the pelvis and sacrum, or the large, triangle-shaped bone at the end of the spine.

Dog Case Study #3 with X-rays and Photos – Dog Skull
The shape of the skull may determine how easy it is for a puppy to pass through the birth canal. Some dog breeds regularly need a veterinarian’s assistance for safe delivery of the litter.

Horse Case Study #1 with X-rays and Photos – Horse Skull
Equine (Horse) Skull
A horse’s skull has large bony ridges and indentions for the attachment of muscles. Large air-filled sinuses in the skull also help to create these large attachment areas without making the head too heavy.

Cat Case Study #1 with X-rays and Photos – Cat Skull
Feline (Cat) Skull
The shape of a kitten’s skull rarely blocks its passage through the birth canal. What is different about a cat skull that makes its birth less complicated than a dog’s or a horse’s birth?

Cat Case Study #2 with X-rays and Photos – Cat Pregnancy
Pregnancy Radiographs (X-Rays)
Radiographs can be used at later stages of pregnancy to see how far along a pregnancy is, as well as determine the number and location of the kittens. What can you see in this close-up image?
Image Caption: Close-up image of feline (cat) pregnancy radiograph.
Try to find the two kittens visible in the abdomen region. During birth they will need to pass through the birth canal that is formed by the pelvis and sacrum, or the large, triangle-shaped bone at the end of the spine.

The pelvis and sacrum (the triangle-shaped bone at the end of the spine) form the passageway that the kittens will have to pass through during birth.
