X-rays produce 2D images and are best for viewing bones, the chest, and detecting simple fractures. They're quick (often taking just seconds), use a relatively low dose of radiation, and usually don’t require sedation. X-rays are a cost-effective and useful first-line diagnostic tool, especially in general practice.

CT scans, on the other hand, create detailed 3D cross-sectional images of the body. They offer significantly higher resolution and are ideal for identifying complex conditions, such as issues involving the brain, spine, internal organs, nasal passages, joints, and tumors. CT scans use a higher dose of radiation (still within safe limits) and typically require sedation or anaesthesia to ensure the patient remains still. Because of the advanced technology involved, CT is more expensive, but it provides diagnostic accuracy that far exceeds standard imaging.

In summary, while X-rays are useful for basic diagnostics, CT scans are essential for getting a full, clear picture in more complex or unclear cases — especially when surgery or specialist treatment is being considered.

The cost of a CT scan can vary depending on your pet’s specific condition and the area being imaged. At Orana Veterinary Imaging, CT scans typically range from $1,500 to $3,000.

In some cases, a consultation with a veterinary specialist may be recommended to determine whether a CT scan is the most appropriate diagnostic option, or if other alternatives should be explored first.

There are two main reasons why CT scans for pets may seem more expensive:

No Government Subsidies for Pet Healthcare

In Australia, human healthcare is supported by a universal system that subsidises many medical services, including CT scans. These are often bulk billed or heavily discounted. In contrast, veterinary care receives no government funding, so the full cost is paid by the pet owner.

Anaesthesia Is Typically Required for Pets

Unlike humans, who can remain still during imaging, pets generally require sedation or general anaesthesia for CT scans. This adds costs for anaesthetic drugs, monitoring, staff time, and recovery care, which are not usually needed for human CT scans.
