Imagine a cat that has fallen from a great height—you need to quickly assess the extent of its injuries. Having equipment that enables fast and accurate diagnosis can make all the difference.
In recent years, many veterinary practices have used refurbished CT scanners (Fan Beam CT or conventional CT) from hospitals due to their lower initial price. However, advancements in imaging technology are making CBCT (Cone Beam CT) an increasingly preferred choice.
But what are the key differences between CT and CBCT, and what are their benefits? Let’s break them down.
Differences in Technology, Costs, and Applications
CT and CBCT both provide 3D imaging but differ in technology, image quality, radiation exposure, and cost. CT uses a fan-shaped X-ray beam with multiple rotations, delivering high-resolution soft tissue imaging ideal for diagnosing internal organs, brain, and thoracic conditions. However, it involves higher radiation exposure and operational costs. CBCT, in contrast, utilizes a cone-shaped beam to capture a single 3D volume, offering lower radiation and faster scan times. While it excels in dental, orthopedic, and skull imaging, it provides limited soft tissue detail. CT is preferred for complex medical cases, while CBCT is a cost-effective choice for bone-focused veterinary diagnostics.
The design of these systems also affects maintenance costs. CT scanners, with their rotating X-ray tubes and detectors, experience greater mechanical wear, resulting in annual maintenance expenses of $50,000 to $100,000. CBCT scanners, with a simpler single-rotation mechanism, require less servicing, reducing maintenance costs to $10,000–$30,000 per year.
X-ray tube longevity further impacts cost efficiency. CT scanners rely on high-powered X-ray tubes that wear out quickly and cost between $50,000 and $100,000 to replace. CBCT scanners use more durable and affordable X-ray tubes similar to those in fluoroscopy systems, typically costing $8,000 to $10,000.
Detector technology also differentiates these systems. CT scanners use multiple detector arrays that require precise calibration and costly replacements. In contrast, CBCT scanners utilize standardized digital flat-panel detectors, which are more affordable while still providing high-quality imaging.
Software and Radiation Shielding
Both CT and CBCT imaging software provide advanced diagnostic capabilities, but there are differences in their associated maintenance costs. CT software typically requires annual fees ranging from $10,000 to $30,000, which can add up over time. In contrast, CBCT systems often include several years of technical support as part of the initial purchase, with renewal fees averaging $3,000 per year, making them a more cost-effective option for long-term support.
When it comes to radiation shielding, CT scanners, with their higher radiation output, require extensive shielding to ensure safety. This can add between $10,000 and $50,000 to installation costs. CBCT scanners, emitting lower radiation levels, have reduced shielding requirements, with costs ranging from $5,000 to $15,000. However, it’s important to note that some local regulations may mandate similar shielding for both systems, so checking with local authorities is crucial before installation.
CBCT’s Multi-Modality Advantage
One of the key advantages of CBCT is its ability to combine fluoroscopy and X-ray imaging into a single system. This integration not only saves valuable space but also reduces costs. A standalone fluoroscopy machine typically requires 500-600 square feet and can cost between $150,000 and $400,000.
By investing in a high-quality CBCT machine, veterinary clinics can streamline their imaging capabilities, cutting both expenses and space requirements. For instance, Detect Vet offers excellent image quality across X-ray, fluoroscopy, and 3D imaging, all within a full 17”x17” field of view, providing a comprehensive solution for veterinary practices.
Making the Best Investment for Your Practice
When you’re comparing CT and CBCT, it’s important to think about both the upfront and long-term costs. While CT scanners offer high-resolution images, they also come with hefty maintenance, replacement, and shielding expenses. On the other hand, CBCT scanners are a more budget-friendly option that requires less upkeep, making them a great fit for most veterinary practices.
Before you decide, take a moment to consider the full cost of ownership—things like maintenance, shielding, and software. If you’re after a versatile, cost-effective imaging solution that still delivers fantastic diagnostic results, CBCT is often the way to go.
