Diagnostic Imaging

Clarity creates confidence
Advancements in diagnostic technology, such as MRI and CT scanners have revolutionized human medicine, giving physicians a level of confidence in their diagnoses unimaginable just a few decades ago. The same caliber of technology has been brought to bear in veterinary medicine in order to advance veterinary medicine’s goal of obtaining good outcomes for our patients.
Boundary Bay Veterinary Specialty Hospital utilizes many imaging techniques such as digital radiography, radiographic contrast procedures, ultrasonography, echocardiography, and high-field magnetic resonance imaging (MRI), to help obtain accurate diagnoses and to guide effective therapy for your pet.

Diagnostic Imaging Service FAQs

What is a board-certified veterinary radiologist?

A board-certified veterinary radiologist is a veterinarian who diagnoses diseases by obtaining and interpreting medical images such as radiographs, ultrasounds, CT scans, and MRIs. In addition to completing an undergraduate university degree and four years of veterinary school, a board-certified veterinary radiologist is similar to his/her human-medicine counterpart in that he/she has completed a residency in the specialized field of radiology (an additional 3-5 years training). In addition to this extensive training, a board-certified veterinary radiologist must pass two rigorous examinations to achieve board certification from the American College of Veterinary Radiology.

What is a radiograph?

A radiograph is commonly referred to as an x-ray. It is a 2D image which can show structures under the skin such as bones and organs.

What is digital radiography?

Digital radiography is a form of x-ray imaging, where digital x-ray sensors are used instead of traditional photographic film. Advantages include time efficiency through bypassing chemical processing and the ability to digitally transfer and enhance images. Compared to conventional radiography, digital radiography is more sensitive and thus uses fewer x-rays (less radiation) to produce an image of similar contrast.

BBVSH uses digital radiography and has 2 digital radiography suites to cut down on wait times.

What is ultrasound?

Ultrasound is a non-invasive, non-painful diagnostic tool that uses sound waves to image the internal architecture of many organs. Sound waves are directed by a probe and are reflected back to the probe by tissue. Ultrasound is effective in finding abnormalities in tissues, because diseased and inflamed tissue often reflect sound waves differently from the healthy surrounding tissues or normal tissues. Normally, ultrasound will be performed on your pet in conjunction with other diagnostic procedures (e.g. blood work, radiographs, biopsies etc). Ultrasound by itself may not be definitive.

BBVSH has two ultrasound machines: one machine is dedicated to the emergency critical care service to help immediately diagnose life-threatening problems (this portable machine can be used “bedside” to avoid moving uncomfortable or critical patients); the second machine is used for in-depth diagnoses and specialized probes for both large and small animals as well as abdominal and cardiac probes are available.

What can be seen with ultrasound?

Ultrasound is very sensitive to changes within abdominal organs and allows precise measurement of heart chamber size and cardiac function. Sonographic changes within abdominal organs are not specific; many disease processes can have a similar appearance on ultrasound examination. Often it is necessary to obtain a needle sample or guided biopsy to determine the exact nature of the changes observed during an ultrasound examination. In general, ultrasound and radiographs (i.e. x-rays) are complementary. In fact, during ultrasound appointments we may request that you allow us to take radiographs if they have not already been done by your family veterinarian. Abdominal radiographs locate region(s) of change within the abdominal cavity and define changes in size, shape or density (e.g. regions of mineralization or gas production). Chest radiographs allow assessment of fluid build-up or abnormal tissue within the lungs and changes in the size and shape of the heart. As ultrasound cannot penetrate air filled structures or regions surrounded by air (i.e. the lungs), radiographs are a starting point to evaluate for heart failure or suspected masses within the chest.

What is an MRI?

Magnetic Resonance Imaging, or MRI, is a non-invasive diagnostic procedure that uses a powerful magnet and radiowaves to produce detailed images of the body’s organs and structures, without the use of X-rays or other radiation.

A computer converts signals from the MRI scan into cross-sectional images of the part of the body that has been scanned. Many images are obtained and each image is a slice of the body area scanned. The images produced by MRI can be compared to a sliced loaf of bread. Just as you can lift each individual slice from the loaf and see both the slice and the inside of the bread, so too the image “slices” produced by the MRI show the details of the inside of the body.

MRI’s are often used to diagnose problems that occur in the brain, spinal cord, and joints.

BBVSH has a 1.5T MRI, which unlike low field magnets used by some veterinary hospitals, can produce images relatively quickly and provides for better diagnostic quality.

What is a CT scan?

A CT scan provides 3D images of bone, soft tissues and blood vessels. Unlike standard radiographs, CT images are 3-dimensional meaning that internal structures do not overlap thereby making diagnoses easier.
CT scans are a painless and non-invasive way to obtain diagnostic images. CT scans, especially those done with 64-slice CT scanners, are extremely fast, and in most cases can be done under sedation only.

BBVSH has a 64-slice CT scanner with an automated contrast injector. A 64-slice CT scanner is 4 times faster than a 16-slice scanner which can be helpful when scanning critical patients some of whom may not even require sedation.

What are CT scans used for?

CT scans may be used for:

  • Diagnosing diseases such as orthopedic disorders; head and neck and spinal cord conditions such as seizures, paralysis, and nasal discharge; and for evaluation of internal organs
  • Detecting internal injuries, internal bleeding, and foreign bodies
  • Diagnosing, staging, and monitoring cancer
  • Guiding procedures such as biopsies and surgeries
