Top vendors for CT Scanners, compared

From hardware distributors and refurbishers to AI reading tools and PET/CT calibration sources — here's what each vendor in this category actually does.

Not all vendors in the CT scanner space sell scanners. Three of the six listed here do: Nati Supply covers new units, refurbished systems, and service contracts with stated nationwide reach — making it a logical first call if you want to compare options across the full CT lifecycle in one conversation. Medical Outfitters Inc. is a multi-manufacturer distributor out of Florida representing named OEMs, with CT coverage running from 16-slice to 128-slice systems. NATIONWIDE IMAGING SERVICES, INC. has been refurbishing and reselling pre-owned GE, Siemens, and Philips CT and PET/CT equipment since 1993 — a strong option if capital budget is the binding constraint.

The other three vendors operate in adjacent segments. MINDWAYS SOFTWARE, INC. makes FDA-cleared software (CliniQCT, QCT Pro) that extracts bone mineral density from CT scans you're already performing — no separate DXA required. Riverain Technologies builds AI tools for chest CT reading, specifically pulmonary nodule detection and coronary artery calcification scoring. ISOTOPE PRODUCTS LABORATORIES, operating as Eckert & Ziegler Isotope Products (EZIP), supplies radioactive QC calibration sources for PET/CT and SPECT/CT systems — it's OEM-qualified for Siemens, GE, Philips, Canon, and United Imaging.

If you're sourcing hardware, focus on the first three. If you're building out what your existing CT infrastructure does, the software and QC vendors become relevant.

How they compare

Hardware: new, refurbished, and what that difference costs you

Slice count is the number that matters most in a CT hardware conversation. A 16-slice system handles routine head and abdominal protocols in a low-volume clinic. A 64-slice or 128-slice unit is what cardiac CT, trauma centers, and high-throughput imaging departments typically require — primarily because higher slice counts cut gantry rotation time and reduce motion artifact. Medical Outfitters Inc. explicitly covers 16- to 128-slice systems and represents named manufacturers including Fujifilm, Ziehm, and others. That defined range and multi-OEM representation is useful if you're specifying a system and want to compare across brands rather than be locked into one.

NATIONWIDE IMAGING SERVICES, INC. takes a different approach — pre-owned and reconditioned inventory sourced from hospitals, refurbished, and resold. They cover multi-slice CT and PET/CT from GE, Siemens, and Philips. For procurement teams working under capital constraints, reconditioned systems can represent meaningful savings, but you should verify the post-refurbishment service record, parts availability horizon, and whether the system has been re-tested to IEC 60601-1 electrical safety standards before accepting. Ask for that documentation upfront. Nati Supply spans both new and refurbished with service contracts, which gives you a single point of contact if your team wants to model total cost of ownership across both options simultaneously.

Pricing for CT systems — new or refurbished — is not publicly listed by any of these vendors. A new 64-slice system from a major OEM typically ranges from roughly $400,000 to over $1,000,000 depending on configuration; reconditioned mid-range units can fall well below that, but publicly verifiable list prices are not available from these distributors. Request itemized quotes and clarify what is included in any service contract.

Software: extracting more value from the CT you already own

If your facility already runs CT, both software vendors here let you expand clinical utility without new hardware capital. MINDWAYS SOFTWARE, INC. has been in quantitative CT bone analysis since 1997. Its CliniQCT and QCT Pro platforms are FDA-cleared and measure bone mineral density from standard CT scans — a meaningful workflow addition for orthopedic screening or opportunistic osteoporosis programs where patients are already being scanned for other indications. This is a software licensing decision, not a capital equipment decision.

Riverain Technologies targets chest CT reading with ClearRead CT Chest, applying AI to pulmonary nodule detection and coronary artery calcification scoring. For radiology groups running high volumes of low-dose CT lung screening (LDCT) under Lung-RADS protocols, AI-assisted detection tools can reduce per-study read time and help flag incidental findings. Integration requirements and workflow fit with your existing PACS or RIS are the practical questions to put to Riverain before committing.

QC infrastructure: calibration sources for PET/CT

ISOTOPE PRODUCTS LABORATORIES (EZIP) is the only vendor here focused on scanner quality control rather than the scanner itself. Their radioactive calibration sources are OEM-qualified for all five major PET/CT and SPECT/CT manufacturers. If your biomed
