They all take pictures, but they don’t show the same things.
If your pet needs imaging, you might wonder why your veterinary team recommends an X-ray, ultrasound, CT or MRI. Each gives us a different view of what’s happening inside:
X-ray: A quick look at bones, the chest and the size and shape of some organs. It can help identify broken bones, changes in the lungs and some swallowed objects.
Ultrasound: A moving, real-time view of organs and soft tissues using sound waves. It helps us examine organs such as the liver, kidneys and bladder, look for fluid or other changes, and guide sample collection when needed.
CT: Detailed images that show the body one thin “slice” at a time. It gives us a closer look at bones, joints, the chest and nasal passages, and can help with surgical planning.
MRI: Highly detailed images of soft tissues using a strong magnet and radio waves. It is especially helpful for examining the brain, spinal cord and nerves, and guiding treatment planning.
The right imaging test depends on the question we’re trying to answer. Sometimes, more than one is needed to help us understand your pet’s condition and plan their care.
