CAT Scan for Veterinary Diagnostic Imaging

Austin Vet Diagnostic Hospital Offers Same Day CAT Scans, Ultrasounds, Digital X-rays, and Laboratory Tests

Our new CAT Scan employs the latest and most precise, rapid, and comprehensive diagnostic imaging available for your pet today.

Located on-site in our hospital and available to use for same-day appointments in most cases, we are pleased to offer the best technological diagnostic options available to ensure top quality veterinary care.

What exactly is CT?

Computed Tomography, also referred to computerized tomography and computerized axial tomography (CAT) is an advanced imaging technique used for diagnostic purposes.

An x-ray tube rotates 360 degrees around the patient while emitting a series of x-rays to form an image using computer analysis of the data collected by multiple detectors. From this data, the computer creates an image of a specific thin slice of tissue (1-10 millimeters). Then this process is repeated and the computer reconstructs the images, like putting slices of bread together in a loaf.

Why are CT Scans Important?

CT allows veterinarians to see images of your pet’s internal organs and structures in great detail from many different angles. This gives them information more quickly, and in many cases, more economically than past tests, conventional x-rays, and exploratory surgeries.

Is CT Like an X-ray?

Yes. CT uses x-rays in conjunction with computer technology to generate images of your pet’s internal organs and structures.

What is involved in a CT Study?

Because CT requires many x-ray beams to penetrate the body at various angles to create an individual image slice, it is crucial that the patient not move during the procedure.

Sedation, or sometimes anesthesia, is therefore necessary. If anesthesia is required, your pet must be fasted overnight prior to the CT scan (no food or water after 10:00 pm). A catheter will be placed in your pet’s leg to be used in the administration of anesthetic drugs, fluid therapy, and occasionally for contrast agents needed for the study. You will be contacted by our staff veterinarian supervising the case once the CT scan is completed, and your pet has recovered from anesthesia.

 

Test Interpretation

The information provided by CT allows for informed decisions to be made about a pet’s treatment by its owner and regular veterinarian. All CT images will be read by our board certified radiologist. The results will be forwarded to your regular veterinarian.

Some Common CT Applications

 

Brain Imaging

Diagnosis of seizure disorders, brain tumors and head trauma

 

Inner Ear

Otitis media/internal

 

Nasal Cavity

Persistant sneezing, nasal discharge, nasal masses

 

Spinal Cord

Intervertebral disk disease, neoplasia, trauma, diskospondylitis

 

Extremities

Lameness, fragmented coronoid processes, joint abnormalities, lytic lesions

 

Thorax

Lung masses, pneumothorax, subtle lymphadenopathy

 

Abdomen

Neoplasia/pathologies of adrenals, pancreas, spleen, liver and kidneys

 

Special Contrast Procedures

Includes ectopic ureters and portosystemic shunts

 

Biopsy Procedures

CT can be used to provide guidance to lesions requiring biopsy. This is particularly useful for lesions that cannot be reliably imaged by ultrasound.
