Computed Tomography is commonly referred to as a CT scan or CAT scan. Computed tomography utilizes rotating x-rays around a patient to make cross-sectional images and is an extremely rapid imaging modality. Modern CT machines can generate hundreds of these cross-sectional images in just seconds. Also modern computer processing can make both two- and three-dimensional reconstructed images from the acquired CT data. Computed Tomography is an important part of imaging at the Veterinary Medical Teaching Hospital at Texas A&M University. Our new Diagnostic Imaging and Cancer treatment center holds a Siemens Somatom 40 slice helical CT scanner. The configuration of this machine allows for imaging of patients that weigh from a few ounces up to nearly 2,000 lbs. Besides dogs, cats, horses and cattle, many other species have been imaged, some of which include birds, mice, lions, llamas, and tortoises. Patients must be absolutely still during the CT imaging process, so general anesthesia (or sometimes heavy sedation in small animal patients) is utilized along with various foam positioning devices to assure proper patient positioning. Many patients that undergo a CT examination also receive intravenous contrast which acts as a "dye" to highlight blood vessels and the vascularity of tissues. CT images are acquired for a wide variety of cases. Most frequently, CT studies are made of spines, skulls, elbows, as well as a wide variety of tumors. In adult horses, we can image the limbs, skull, guttural pouches, TMJ's, and often the first few vertebrae. Computed tomography not only aids in the diagnosis of disease and patient prognostics, but it is also used as a tool in the planning of the patient's treatment options.


A Bengal tiger is being readied for a CT exam of the spinal column.


This is a CT image of a cat at the level of the brain and middle ear. This patient has an infection of the middle ear cavity (otitis media, arrowhead).


CT scan of a normal yearling horse skull. The teeth, sinus cavities, brain, guttural pouches, TMJ’s, and ear cavities can all be evaluated.

3D rendering of a CT scan of a horse tarsus (hock). This imaging is helpful for surgical planning.

3D rendered CT scan of a cat abdomen, highlighting contrast enhanced structures. The kidneys, spleen, and major vessels (aorta and caudal vena cava) are shown. The curving vessel at the top of the image is an abnormal shunt, directing blood around the liver. This imaging is helpful for surgical planning.

Interpretation of Referral Images

Our board certified veterinary radiologists offer interpretation of radiographic images made by referring practices. This includes interpretation of the following diagnostic imaging modalities (radiography, CT, and MRI). A radiographic interpretation will be provided, both with telephone and written report, within 1 business day following the receipt of the images and information form.

This service is provided during normal weekday business hours. No afterhours, weekend, or STAT interpretation is currently available.

How to submit a case for interpretation

To submit a case for interpretation, you must first do both of the following:

  1. Call 979-845-9081 to receive image upload (or delivery) instructions, provide billing information, and receive client-patient information form
  2. And submit client-patient information form to . (Only this email address should be used to submit the form and requests for interpretation.) Please include the DVM’s name and Hospital into the subject line.

Interpretation can only proceed following receipt of billing information (referring DVM), client information, and patient information (including signalment and pertinent history).

Images transferred in DICOM format are preferred. TIFF and JPEG images can be submitted but may be of lesser diagnostic quality. (No smaller than 150 DPI, Pixels/inch)
