Buyer’s FAQ
CT Scanner Buyer’s FAQ
The questions hospitals and imaging centers ask us most often before buying a new or refurbished CT scanner — covering price, technology, site planning, service, and reimbursement.
Cost and Budget
How much does a CT scanner cost — new vs refurbished?
New CT scanners range from $300,000 for a basic 16-slice system to $2.5 million or more for advanced multi-energy platforms. Refurbished CT scanners typically cost 30 to 50 percent less — a refurbished 64-slice can be found for $150,000 to $400,000. The best price on a certified pre-owned CT depends on model year, slice count, software version, and included warranty. New vs used: new systems offer longer support life and current software; refurbished systems offer faster ROI. Always request a fully itemized quote that separates equipment cost, installation, training, and service contract.
What is the total cost of ownership for a CT scanner over 7 to 10 years?
Beyond the purchase price, total cost of ownership for a CT includes annual service contracts, X-ray tube replacements, and software upgrades. CT X-ray tubes cost $40,000 to $100,000 and typically last 200,000 to 400,000 scans before needing replacement. Annual service contract fees run 8 to 12 percent of the original equipment cost. Preventive maintenance visits — typically twice yearly — are included in most service contracts. Ask vendors to provide a 10-year cost model including tube replacement cycles and software upgrade paths.
What financing options exist for purchasing a CT scanner?
Equipment loans, operating leases, capital leases, and vendor financing programs are all widely available. Lease vs buy: leasing allows you to upgrade to newer technology at the end of the term without a large capital outlay. Operating leases allow monthly payments to be expensed and keep the debt off the balance sheet. Many vendors and third-party lenders offer deferred start programs — no payments for 6 to 12 months after installation. Discuss financing options with your CFO and the vendor’s financial team early in the purchasing process.
Technology and Specifications
How many CT slices do I need — 16, 64, 128, or 256-slice?
16-slice CT handles routine diagnostic imaging, emergency radiology, and trauma at the most affordable price point. 64-slice CT is the most widely used in clinical practice — suitable for cardiac, pulmonary, and high-volume general radiology. 128-slice and above enables advanced cardiac CT angiography, dual-energy imaging, and spectral CT protocols. Higher slice count reduces scan time (less motion artifact) and improves coverage — especially important for cardiac and pediatric imaging. What is the difference between 64-slice and 128-slice? Primarily speed, cardiac capability, and advanced reconstruction options.
What is low-dose CT and why is dose reduction important when buying?
Low-dose CT uses iterative reconstruction algorithms to reduce patient radiation exposure by 30 to 80 percent versus standard filtered back-projection. FDA cleared dose reduction technologies include ASIR (GE), SAFIRE (Siemens), iDose (Philips), and AIDR (Canon). Dose reduction is critical for pediatric imaging, lung cancer screening programs, and high-volume CT operations. Buying a system without modern dose reduction technology is increasingly difficult to justify clinically and legally. Ask vendors for published dose comparison data on the specific model you are evaluating.
What is dual-energy or spectral CT and should I buy it?
Dual-energy CT (DECT) acquires data at two different energy levels simultaneously, enabling material decomposition and virtual non-contrast imaging. It improves characterization of kidney stones, gout, liver lesions, and pulmonary emboli — among many other applications. Spectral or photon-counting CT (the latest generation) takes this further with detector-level energy discrimination. What is the difference between standard CT and dual-energy CT? Primarily the ability to characterize tissue composition, not just anatomy. Dual-energy capability adds $150,000 to $400,000 to the purchase price depending on implementation method.
Installation and Site Planning
What room and radiation shielding requirements does a CT scanner need?
CT uses ionizing X-rays — a radiation-shielded room is mandatory and must be designed by a qualified medical physicist. Do I need a radiation room? Yes. Concrete, lead, or a combination of shielding materials are required based on workload calculations. Room construction costs typically range from $50,000 to $200,000 depending on existing structure and shielding requirements. Site planning must also address floor load (CT gantries can weigh 1,000 to 2,000 kg), electrical, and cooling requirements. Your vendor should provide site planning drawings and a physics workload analysis as part of the pre-sale process.
How long does CT installation take and what is the lead time?
Lead time for a new CT scanner is typically 8 to 16 weeks from order confirmation to delivery. Site preparation — including radiation shielding construction — should begin as soon as the order is placed. Physical installation of the CT system typically takes 3 to 7 days once the room is ready. Total lead time from contract signing to first patient scan: 3 to 6 months for new; 2 to 4 months for refurbished. How long does installation take if the room is already built? About 1 week for installation plus 1 to 2 weeks for calibration and acceptance testing.
Service, Warranty, and Support
What service contract and warranty should I expect with a CT scanner?
New CT scanners typically include a 1-year parts and labor warranty from the manufacturer. Extended service contracts provide coverage for preventive maintenance, emergency repairs, X-ray tube replacement, and software updates. OEM vs aftermarket: OEM contracts are more expensive but include factory-trained engineers and original parts. Independent service organizations (ISOs) often offer comparable uptime guarantees at 20 to 40 percent lower cost. Always clarify: Does the service contract include X-ray tube replacement? This is a major cost item.
How do I evaluate parts availability and long-term support for a CT system?
Parts availability depends on the model’s age and the manufacturer’s declared end-of-support timeline. Ask: How many years of parts and software support remain for this specific model? Major CT manufacturers typically support systems for 10 to 15 years post-production. For refurbished CT systems, confirm parts availability in writing as part of the purchase agreement. Choosing a high-volume platform from a major manufacturer reduces long-term obsolescence risk.
Workflow and Integration
How does a CT scanner integrate with PACS and hospital systems?
All modern CT scanners are DICOM compatible — this ensures seamless data transfer to your PACS. PACS integration should be tested during the installation and acceptance process, not assumed. CT systems also integrate with RIS via HL7 messaging for automated order routing and worklist management. AI-powered post-processing software (for lung nodule detection, stroke triage, etc.) requires additional DICOM networking. Confirm network bandwidth requirements with your IT team — high-slice CT generates very large image datasets.
What training is provided for CT technologists?
Application training from the vendor is typically 3 to 5 days on-site at installation — confirm whether training provided is included in price. Training should cover protocol setup, dose optimization, patient positioning, quality control, and emergency procedures. Phantom-based quality control training is especially important for low-dose CT and lung cancer screening programs. Online and remote training modules are offered by most major vendors for ongoing staff education. Budget $5,000 to $15,000 for additional external training if your team is new to CT operations.
Clinical and Regulatory
Is CT FDA cleared and what regulatory compliance is required?
All CT scanners sold in the United States must be FDA cleared as Class II medical devices. Facilities must comply with state radiation control agency regulations — annual physics surveys are required in most states. For lung cancer screening programs, the CT system must meet ACR CT Accreditation requirements. Low-dose CT lung screening programs require ACR or IAC accreditation for Medicare reimbursement. Your medical physicist should perform an acceptance test and baseline dose survey before clinical use begins.
Is CT reimbursed by Medicare and insurance, and how does that affect ROI?
CT imaging is reimbursed by Medicare, Medicaid, and most commercial payers when medically indicated. Is it covered by insurance? Yes — reimbursement rates vary by CPT code, body part, contrast use, and facility type. Hospital outpatient CT reimbursement from Medicare ranges from approximately $100 to $600 per scan. Lung cancer screening CT (LDCT) is covered by Medicare at 100 percent for qualifying patients under USPSTF guidelines. Work with a healthcare revenue cycle consultant to model expected volume and reimbursement before finalizing your business case.
Vendor Evaluation
How do I compare CT vendors and which brand is best?
The leading CT manufacturers are Siemens Healthineers, GE HealthCare, Philips, and Canon Medical. How do I compare vendors? Key factors include image quality benchmarks, dose performance, service network coverage, and software ecosystem. Which brand is best depends on your volume and clinical focus — GE and Siemens dominate high-volume sites; Canon is strong in dose performance. Request a side-by-side demo at a reference site with your own imaging protocols before making a final decision. Check independent service coverage maps in your region — not all OEM service networks are equally dense in every geography.
Should I buy new or refurbished CT — what are the real risks of refurbished?
Refurbished CT scanners from reputable certified pre-owned vendors are a legitimate and widely used option. Key risks of refurbished CT: shorter remaining support life, potential software limitations, and tube age. Mitigate risk by requiring: a detailed inspection report, remaining tube scan count, warranty of at least 12 months, and parts availability commitment. New vs used risk comparison: new has higher upfront cost but lower operational risk; refurbished has lower entry cost but requires more due diligence. Always ask the seller for the system’s full service history and any prior defects or major repairs.
What questions should I ask a CT vendor before signing a purchase agreement?
Is the system FDA cleared and what software version is included at delivery? Is installation included in the quoted price — what exactly does it cover? What warranty is provided and does the service contract include tube replacement? What financing options are available and can payments be deferred during site preparation? What is the lead time from contract to first scan and what are my responsibilities for site readiness?
Patient and Operational
How does CT work and how do I explain radiation dose to patients?
CT uses a rotating X-ray source and detectors to acquire cross-sectional images of the body — reconstructed into 3D views. How does it work? The gantry rotates around the patient while an X-ray beam is attenuated differently by different tissues. Radiation dose from a CT scan varies by body part: a chest CT delivers approximately 7 mSv; a head CT approximately 2 mSv. Low-dose CT protocols reduce exposure significantly — a low-dose chest CT for lung cancer screening delivers less than 1.5 mSv. Patients should be counseled that the diagnostic benefit of CT imaging far outweighs the small associated radiation risk.
What is the difference between CT and MRI and when should I buy which?
CT is faster, less expensive per scan, and better for bone, vascular, lung, and trauma imaging. MRI offers superior soft tissue contrast with no radiation — preferred for brain, spine, musculoskeletal, and oncological imaging. What is the difference between CT and MRI in terms of cost? CT scanners are generally less expensive to purchase and operate. High-volume emergency departments, trauma centers, and pulmonary programs benefit most from CT investment. If your clinical program requires both, plan the CT first for volume and revenue, then add MRI for clinical breadth.
Can a CT scanner be upgraded later and what is the upgrade path?
Most major CT platforms support software upgrades including new clinical applications, dose reduction packages, and AI tools. Hardware upgrades — such as adding detector rows to increase slice count — are generally not possible mid-life. Can I upgrade later? Software yes; hardware slice count no — your slice count is determined at purchase. AI-powered clinical decision support tools can be added post-installation as software modules on most current platforms. Ask the vendor for the full upgrade roadmap and future-year software pricing before signing the purchase agreement.
