A new CT scanner costs anywhere from $285,000 for a basic 16-slice system to over $2 million for a premium 256-slice machine. Refurbished models cut that roughly in half, with entry-level options starting around $80,000 to $95,000. But the purchase price is only part of the picture. Annual maintenance, tube replacements, software add-ons, and electricity can add tens of thousands of dollars per year to the total cost of ownership.
New CT Scanner Prices by Slice Count
The single biggest factor driving price is the number of slices a scanner captures per rotation. More slices mean faster scans, sharper images, and the ability to handle specialized work like cardiac imaging. Here’s what new systems cost at each tier:
- 16-slice: $285,000 to $360,000. Suitable for general diagnostic imaging in smaller clinics and urgent care centers.
- 64-slice: $500,000 to $700,000. The standard for cardiac CT angiography and most hospital-level imaging. Scanners at this level can achieve rotation times fast enough to minimize blurring from a beating heart.
- 128+ slice: $675,000 to $1 million. Found in specialty practices and high-volume hospitals that need speed and resolution for complex cases.
- 256+ slice: $1.35 million to $2.1 million. Research-grade and advanced cardiac systems. These are the top of the market.
Software packages push the price higher. A cardiac imaging software suite alone runs $35,000 to $100,000, while a lung analysis application adds $15,000 to $35,000. These aren’t always included in the base price, so the sticker number you see in a quote may not reflect what you actually need to spend.
Refurbished and Used Scanner Pricing
Refurbished CT scanners offer the most common path to significant savings. On average, a certified refurbished unit costs about 50% less than its new equivalent. Scanners sold “as-is” without refurbishment can go for as little as 25% of the original price, though those carry more risk. Certified refurbished systems, which have been inspected, repaired, and tested, typically land around 75% of the original sticker price.
For specific refurbished models on the market in 2025:
- GE Optima RT: starting at $95,000
- Siemens SOMATOM Emotion: starting at $105,000
- Toshiba Aquilion 64: starting at $115,000
Refurbished pricing by slice count follows a similar tiered pattern. A refurbished 16-slice runs $90,000 to $205,000, a 64-slice costs $175,000 to $390,000, and a 128-slice or higher ranges from $225,000 to $650,000. The spread within each tier reflects the age of the system, the brand, the condition of the X-ray tube, and how many scan hours are already on it.
Annual Maintenance Contracts
Service contracts are one of the largest recurring expenses. Competitive contracts, where a facility shops among multiple service providers, average around $70,000 per year. Sole-source contracts, where the original manufacturer is the only option, average roughly $124,000 per year, about 76% more. That difference alone can add up to hundreds of thousands of dollars over a scanner’s lifetime.
These contracts typically cover preventive maintenance visits, emergency repairs, and replacement parts. What they don’t always cover is the most expensive single component in the machine: the X-ray tube.
X-Ray Tube Replacement
The X-ray tube is the part of the scanner that generates the imaging beam, and it wears out with use. A study tracking GE LightSpeed and VCT scanners over six years found that tubes lasted an average of 19 to 22 months before needing replacement, though individual tubes ranged anywhere from 7 to 48 months depending on scan volume.
Replacement costs vary dramatically by model and by where you source the tube. Buying directly from the original manufacturer is the most expensive route. For example, a factory tube for a GE LightSpeed runs about $145,000, while a Siemens Sensation 64 tube costs around $210,000. Third-party and aftermarket tubes cost significantly less. A used tube with moderate wear for that same GE LightSpeed drops to $20,000 to $25,000, and aftermarket options for GE models range from $20,000 to $95,000 depending on the scanner.
For a high-volume facility replacing tubes every 18 to 24 months, this is a cost worth planning for from the start. A single tube replacement on a premium system can rival what a small clinic paid for its entire refurbished scanner.
Electricity and Facility Costs
A CT scanner consumes roughly 26,000 kilowatt-hours of electricity per year. At typical U.S. commercial electricity rates, that translates to about $4,000 to $5,000 annually. What’s notable is where that energy goes: a University Hospital Basel study found that scanning itself accounts for a relatively small share of total consumption. The majority of energy is used while the machine sits idle but powered on, consuming about 14,300 kWh per scanner per year just in standby mode. Facilities that power down scanners during off-hours or use automated sleep modes can trim that figure meaningfully.
Beyond electricity, installing a CT scanner requires site preparation. The room needs reinforced flooring to support the machine’s weight (often several tons), radiation shielding in the walls, dedicated electrical circuits, and climate control. These buildout costs vary widely by facility but can run $50,000 to $150,000 or more for a new installation.
Total Cost of Ownership
Looking at a five-year window gives a more realistic picture than the purchase price alone. Take a mid-range new 64-slice scanner at $600,000. Add a competitive service contract at $70,000 per year ($350,000 over five years), two tube replacements at roughly $50,000 to $75,000 each using aftermarket parts, $25,000 in electricity, and $50,000 in software. The five-year total lands somewhere around $1.1 to $1.2 million.
A refurbished 64-slice at $250,000 with the same operating costs still reaches $700,000 to $800,000 over five years. The purchase price savings are real, but ongoing costs eventually dominate the budget regardless of whether you bought new or used. For any facility evaluating a CT purchase, the service contract terms and tube replacement strategy matter almost as much as the price on the invoice.
