Dog Diagnostic imaging at Markham Woods Animal Hospital

Dogs often have lumps and bumps and other things that we can see as pet owners that signal to us that it’s time for a trip to the veterinarian. However, that doesn’t tell the whole picture. Just as with humans, we need to know what’s going on inside dogs. This is particularly true if they’re showing symptoms that something is wrong, but there’s no outward indication of this. This is why x-rays are such a helpful and important diagnostic tool for us!

What is veterinary diagnostic imaging?

Veterinary diagnostic imaging is a completely painless and non-invasive collection of tools to assess your dog’s health.

Veterinary diagnostic imaging includes the following:

  • Radiographs (x-rays)
  • Ultrasound
  • CT scans
  • MRIs

We use these images to gather information on your dog to assist them in making a medical decision, a treatment plan, and sometimes a surgical plan.

How does diagnostic imaging help diagnose my pet?

Diagnostic imaging (x-rays or ultrasound) helps us get a picture of what's going on inside your pet. We look for things that might be out of place or things that shouldn't be there, or diseases that may be going on that we can visibly see on the inside of your pet. Imaging allows us to safely look inside your pet without getting more invasive to do so.

For instance, if your dog is vomiting, we may take an x-ray to look for possible causes, such as obstruction of the intestines or an obvious foreign body. The x-ray may show some signs of intestinal obstruction. Most of the time we can diagnose with ourselves with our in house radiograph system. There are times that we do need to call a Veterinary Radiologist to look at the x-rays to get their medical opinion on them. We also may refer you to them if we feel that there is additional internal imaging that is needed.

What does a veterinary radiologist do?

A veterinary radiologist does extra schooling after veterinary school to become certified and specialized in all diagnostic imaging forms. A veterinary radiologist is someone that we would refer you to a specialty hospital to see. We would do that mainly for things like MRIs or CT scans. In these instances, there’s often something more specific that we need to diagnose; we may need a second opinion, or something doesn't make sense to us. In those cases, we like to have a professional look at them, so we would send the x-ray over to have a veterinary radiologist read it, review it, and give us their opinion.

What are some of the things that diagnostic imaging looks for?

Many times what we're looking for is something that's not quite right with your pet. If we're looking at an x-ray of their chest, for example, we're looking at their heart and lungs, so we're looking for abnormalities in those two things. If we're looking at an x-ray of their belly, we might be looking at their different organs to look for tumors or at their intestines to see if they've eaten something. We're seeking more information about why we see the symptoms we see in the dog. We can also look for congenital issues. We see hernias and many other things when we take x-rays.

Ultrasound is a bit more specific for looking inside the organs. we would most likely refer you to a specialist if an ultrasound is needed. With an ultrasound they can more easily see masses that might be hiding, evaluate the gallbladder, and look at the kidneys, bladder, and adrenal glands, which are so small that you can't see them on an x-ray. We're also looking for a thickening of the intestines. So the ultrasound is a lot more sensitive and specific for different diseases that we may not be able to diagnose as well with the x-ray.

The ultrasound doesn’t give you a good picture of the chest, except for the heart, so if someone says you need an echocardiogram, that would be an ultrasound of the heart. And that would be something that a veterinary cardiologist would do, although it's still considered diagnostic imaging.

Is diagnostic imaging safe for my dog?

Yes. We do x-rays so infrequently on dogs that the amount of radiation they're exposed to is so minimal that it's very safe. Its generally over so quickly that they are done before they even realize anything is happening.

Ultrasound imaging is also very safe. It's the same thing techs use for imaging babies in the womb, so there are no side effects to it at all. It is an excellent way to get more information about your pet without doing something more invasive or harmful to them. So it's a way that your doctor can get more information on what's going on with your dog without doing anything that might potentially cause them pain.

Would my dog need to be sedated for diagnostic imaging?

Most of the time, no, as we can get the information we need without sedation. There are some cases where we may want to sedate your pet. And most of the time, that's because we're looking for a specific view that might be uncomfortable for the pet while we're manipulating their limbs. For example, x-rays to look for hip dysplasia typically work best under anesthesia because you're pulling on their legs to get the best possible image, and it's just not fair to the dog to ask them to hold still while we're doing that. Most animals are excellent, and we don't need to do any sedation. Every once in a while, we'll get a cat or a dog that'll be nervous and might need some, but most of the time, we're very upfront with you about whether your dog would need some sedation to do that. The vast majority of dogs are fine without sedation during diagnostic imaging.

If you feel your pet may need x-rays we’d love to see your dog for diagnostic imaging, and a consultation and get to the heart of whatever is ailing them. Please don’t hesitate to call us at (407) 682-3233 or email us at [email protected].
