The CT Procedure

Anesthesia is necessary to ensure that your pet remains motionless during the procedure. While under anesthesia, your pet will be continuously monitored by a veterinarian. After your pet is anesthetized and positioned for the scan, an initial “scout” view is obtained. A series of thin image slices is then collected through the area of interest. Contrast medium containing iodine may then be injected into an intravenous catheter to enhance CT visualization of blood vessels or structures such as ureters, or to sharpen the margins of tumors or other lesions. If needed, and after discussion with you, biopsy of identified lesions can also be performed using CT or ultrasound guidance.

The post-anesthesia recovery period is typically brief. The CT scan findings will be discussed with you at this time, and then relayed to your veterinarian.In addition to a written report, your veterinarian will be provided with access to the full study for review.

The Ultrasound Procedure

Most pets require no sedation and lay quietly for the procedure.

Especially nervous or wiggly patients may need sedation to enable a thorough examination although we find this infrequent. Sedation or brief anesthesia is usually employed if a biopsy or needle aspirate procedure is performed.

Once you arrive for your appointment, we will clip your pet’s fur and apply ultrasound gel. Your pet will be placed on our ultrasound table while the doctor performs the ultrasound. If you wish to be present for the ultrasound we can accomodate you.

The doctor will review the findings with you at the time of the study.  Results will be provided to your veterinarian in the form of a written report.  Your veterinarian will also be provided with access to the images for review.


+ Is fasting required for a CT?

Yes, because this procedure is done under anesthesia your pet should have no food for 8 hours before the appointment. Your pet can have free access to water.

+ How long will it take?

The total time of the appointment is usually between 1.5 and 2 hours.

+ When will I have the results? When will my veterinarian have them?

We will go over the results with you during the appointment. Your veterinarian will be called at this time, and will receive a copy of the written report and the CT within a few days.


+ Why does my pet’s fur need to be clipped?

The role of fur or hair is to trap air near the skin in order to regulate body temperature. Unfortunately, ultrasound waves cannot pass through air. The fur must be clipped in order to obtain a clear picture.

+ Does my pet need to fast for an ultrasound?

We ask that you withhold food from your pet for 8 hours before your appointment. Water is allowed.

+ What if my pet licks off the ultrasound gel?

Ultrasound gel is not harmful to your pet. It is non-toxic, water soluble, odorless, colorless, and will not stain. We will try to remove as much gel as possible after the ultrasound, but some may remain.
