A CT scanner costs anywhere from $100,000 to $3 million, with the final price depending on whether you buy new or refurbished, how many detector slices the system has, and the brand. That’s a wide range, so understanding what drives the price up or down is essential before budgeting for one.
New CT Scanner Prices by Type
The single biggest factor in price is the number of detector slices a scanner can capture per rotation. More slices mean faster scans, better image resolution, and a higher price tag. A basic 16-slice CT scanner, suitable for routine imaging at a small clinic or urgent care center, typically falls in the $150,000 to $400,000 range when purchased new. Mid-range systems with 64 slices, which cover most diagnostic needs including cardiac imaging, generally run from $400,000 to over $1 million.
High-end systems with 128 or 256 slices, used in large hospitals and academic medical centers for advanced cardiac, neurological, and trauma imaging, push into the $1 million to $3 million range. These premium scanners offer features like dual-energy imaging, ultra-fast rotation speeds, and lower radiation doses, all of which add to the cost.
Specialized Scanners Have Different Price Points
Not every facility needs a full-body CT system. Dental practices commonly use cone beam CT (CBCT) machines, which are smaller and purpose-built for imaging teeth, jaws, and sinuses. A small-to-midsize CBCT machine typically costs $50,000 to $100,000, making it far more accessible than a traditional medical CT scanner.
Mobile CT units, which are built into trailers or specially designed vehicles for use in stroke ambulances or temporary field hospitals, carry a premium for their portability. A new mobile CT system runs approximately $1.2 million, factoring in the vehicle customization and setup. Refurbished mobile units in good to excellent condition can be found for around $200,000.
Refurbished Scanners: Significant Savings
Buying refurbished is one of the most common ways facilities reduce upfront costs. Refurbished CT scanners are systems that have been deinstalled from another site, inspected, repaired as needed, and restored to full working condition. Prices start around $100,000 for older or lower-slice models and can reach $500,000 to $800,000 for refurbished 64-slice systems that would cost well over $1 million new.
The trade-off is that refurbished systems may lack the newest software features, could have older detector technology, and will have a shorter remaining useful life on key components. That said, for many community hospitals, outpatient imaging centers, and international buyers, a quality refurbished scanner covers the clinical need at a fraction of the cost.
The X-Ray Tube: Your Most Expensive Replacement Part
The X-ray tube is the heart of any CT scanner, and it wears out over time. Replacing it is one of the largest ongoing expenses you’ll face, and the cost varies dramatically depending on your scanner model. Data from Block Imaging, a major medical equipment reseller, shows just how wide the range is.
For an older GE HiSpeed system, a brand-new tube from the original manufacturer costs around $42,000, but you can buy a low-use replacement for $12,000 to $14,000. At the other end of the spectrum, a new tube for a Siemens Sensation 64-slice scanner costs $210,000 from the manufacturer, with even low-use replacements running $100,000 to $120,000. Philips 64-slice systems fall in a similar bracket, with new tubes at $193,000 and used options starting around $55,000.
Aftermarket tubes, made by third-party manufacturers, offer a middle ground. Where available, they typically cost 40% to 60% of the original manufacturer’s price. For example, an aftermarket tube for a GE VCT 64-slice system runs $75,000 to $85,000 compared to $154,000 from GE. Not every model has an aftermarket option, though, particularly newer Siemens and Philips systems.
Annual Maintenance and Service Contracts
Beyond the purchase price, plan for ongoing service costs. Most facilities sign an annual service contract with the scanner manufacturer or a third-party service provider. These contracts cover preventive maintenance, emergency repairs, and sometimes parts replacement.
As a general benchmark, annual service contracts typically cost 8% to 12% of the scanner’s original purchase price. For a $500,000 scanner, that translates to roughly $40,000 to $60,000 per year. For a premium $2 million system, you could be looking at $160,000 to $240,000 annually. Third-party service providers often undercut the original manufacturer’s pricing by 20% to 40%, though coverage terms and response times vary.
Some facilities opt out of full service contracts and instead pay for repairs as they come, sometimes called “time and materials” arrangements. This approach can save money in good years but leaves you exposed to a six-figure tube replacement with no warning.
Software, Installation, and Hidden Costs
The sticker price of the scanner itself doesn’t capture everything you’ll spend. Site preparation is a major additional cost. CT scanners require specific room dimensions, reinforced flooring to handle the weight (which can exceed 5,000 pounds), lead-lined walls for radiation shielding, and dedicated electrical and cooling systems. Depending on whether you’re retrofitting an existing room or building new, site prep can add $50,000 to $300,000 or more.
Software licensing is another ongoing expense. Medical imaging platforms that handle viewing, storing, and sharing scans typically charge monthly subscription fees. Basic plans start around $100 to $130 per month, while more feature-rich systems run $300 to $400 per month per location. Setup fees of $500 to $1,000 per site are common. Enterprise-level systems with full integration into hospital information systems are priced on a custom basis.
Training staff to operate the scanner, purchasing or upgrading workstations, and connecting to your facility’s image storage system all add incremental costs that are easy to overlook during the purchasing process.
Total Cost of Ownership Over Five Years
When you add up the purchase price, installation, service contracts, at least one tube replacement, and software, the total five-year cost of ownership for a CT scanner is substantially more than the initial number on the quote. A mid-range 64-slice system purchased new at $750,000 might carry a five-year total cost of $1.2 to $1.5 million once you factor in $250,000 to $350,000 in service contracts, a $75,000 to $150,000 tube replacement, and $100,000 or more in site preparation and software.
For a refurbished system purchased at $250,000, total five-year costs might land in the $500,000 to $700,000 range, though higher repair frequency on older equipment can narrow the savings gap. Running the full cost-of-ownership calculation, not just the purchase price, is what separates a good buying decision from an expensive surprise.
