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.

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:
- Call 979-845-9081 to receive image upload (or delivery) instructions, provide billing information, and receive client-patient information form
- And submit client-patient information form to firstname.lastname@example.org . (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)
- Radiographic Interpretation (<10 Images): $68
- Radiographic Interpretation (≥ 10 images): $80.00
- MRI/CT Interpretations= $100.00 for primary area (i.e. spine, thorax, abdomen, head, pelvis, limb; post-contrast images included), $50 for each secondary area.
