When it comes to diagnosing and treating health conditions in our furry friends, veterinarians sometimes need to take a closer look at their internal anatomy. That’s where CT scans come in. Similar to traditional X-rays, a CT scan uses computed tomography to obtain detailed images of an animal’s organs, muscles, bones, and other internal body parts. These images are then reconstructed into three-dimensional models, providing valuable information for diagnosis and treatment planning.
Why Do Pets Need CT Scans?
CT scans play a crucial role in understanding anomalies in an animal’s body and planning for surgeries. For example, when a surgeon needs to locate a tumor precisely and assess its relationship to neighboring structures, a CT scan provides the necessary information to plan the surgical approach. This is particularly vital for liver and pulmonary tumors. CT scans are also essential in identifying or ruling out metastasis in cases of cancer, helping veterinarians determine the extent of the disease and plan the appropriate treatment.
Apart from cancer, CT scans are useful in evaluating nasal disease in dogs and cats with chronic nasal discharge. They are also valuable for understanding orthopedic abnormalities and planning corrective procedures. Dentists use CT scans to examine tooth decay and abscesses, while in cases of poly-trauma where multiple organs and systems are damaged, CT scans provide valuable insights into the severity and complexity of injuries.
However, it’s important to note that CT scans are not the ideal diagnostic tool for neurology patients. For brain and spinal cord diseases, an MRI is generally a better option.
How are CT Scans Conducted?
CT scans are typically performed at large hospitals, including university teaching hospitals, due to the need for skilled technicians and specialized equipment. The process begins with the patient being held off food the night before the exam. Upon arrival at the facility, blood work is taken, and the animal is prepared for anesthesia.
Once under anesthesia, a veterinary technologist positions the animal, and the scan is performed by a team consisting of a technologist and anesthesiologist in a separate room. Everyone can monitor the animal and her vitals through a large window. Each scan takes only about 30 seconds, and the anesthesiologist periodically checks on the animal in between. The entire procedure, from anesthesia to waking up, usually takes about 45 minutes.
In some cases, the scan may be conducted twice, with the second scan involving an injection of iodine. This additional scan allows radiologists to observe abnormal iodine intake, which can indicate inflammation or tumors. A report is generated immediately after the exam and is typically available to the referring veterinarian within hours.
Are There Any Side Effects to a CT Scan?
For dogs and cats, there are typically no side effects associated with CT scans. Unlike humans who may develop an increased risk of radiation-induced cancers after multiple CT scans, these risks are rare in animals. Additionally, the shorter lifespan of pets means they are unlikely to be affected in this way. However, as with any procedure that requires anesthesia, it is important to monitor the patient for a short period following the scan for any potential ill effects.
How Much Do CT Scans for Pets Cost?
The cost of a CT scan for pets can vary depending on the complexity of the scan and the study. For scans that require the injection of iodine, the total cost of the procedure could reach up to $1,000. It’s important to note that costs can also vary depending on the veterinarian and geographic location.
In metropolitan areas like New York City, the total cost of a CT scan—including consultation, examination, blood work, anesthesia, hospitalization, and the scan itself—can range from $1,500 to $2,500.
Frequently Asked Questions
Q: Are CT scans painful for pets?
A: No, CT scans are not painful for pets. They are performed under anesthesia to ensure the animal remains still and comfortable throughout the procedure.
Q: How long does it take to receive the results of a CT scan?
A: The results of a CT scan are typically available to the referring veterinarian within hours of the exam.
Q: Are CT scans covered by pet insurance?
A: It depends on the pet insurance policy. Some policies may cover the cost of CT scans, while others may have specific limitations or requirements. It’s best to check with your insurance provider to understand the coverage details.
Conclusion
CT scans are a valuable diagnostic tool in veterinary medicine, providing detailed images of an animal’s internal anatomy. They play a vital role in diagnosing various conditions, planning surgeries, and understanding the extent of diseases such as cancer. While the cost of CT scans can vary, they are an essential investment in the health and well-being of our beloved pets.
