Large imaging systems hold their clinical usefulness far longer than their commercial life. A CT scanner installed eight years ago produces images a radiologist is perfectly happy to report on. That gap is the whole refurbished market, and it is a real one — but the word "refurbished" covers everything from a factory programme with a warranty to a machine that was switched off, moved, and switched on again.
The three grades that actually exist
- Manufacturer-refurbished. Returned to the original manufacturer's programme, brought to a defined specification, re-certified, and sold with a warranty comparable to new. The most expensive refurbished option and the only one where the manufacturer stands behind the result.
- Third-party refurbished. A specialist strips, replaces wear parts, re-tests to a published protocol and warrants its own work. Quality here ranges from excellent to nominal, and the difference is the protocol — ask to see it.
- De-installed and re-sold. The machine works. Nothing has been replaced. This can be a sound purchase at the right price if you know the site history, and a very poor one otherwise.
What decides the real cost
For CT, the tube. An X-ray tube is a consumable with a life measured in scan-seconds, and it is the single most expensive part of the system. A scanner quoted cheaply with a tube near end of life is not cheap; it is a scanner plus a large near-term invoice. Ask for the tube's remaining life in scan-seconds or exposures, in writing, and treat it as part of the price.
For MRI, the magnet and the cold head. A magnet that has been ramped down and transported is a different risk from one moved under field. Helium handling, the cold head's age and the chiller's condition drive the running cost more than anything on the spec sheet.
For both, software licensing. Clinical application licences do not always transfer with the hardware, and a system that arrives without the licences your protocol depends on is a system your radiologists will refuse. Get the licence list, by name, and confirm transferability with the manufacturer rather than with the seller.

Site works are not a rounding error
Installing large imaging equipment means power, cooling, floor loading, radiation shielding and a route into the room. On a refurbished purchase these costs are identical to new, which means they consume the saving proportionally faster. A refurbished system that saves 45% on equipment might save 25% on the delivered project — still worth having, but a different number from the one in the quotation.
Where refurbished is usually wrong
Two situations. First, when the clinical requirement is a capability that only exists on current-generation hardware — a specific reconstruction, a dose-reduction technique, a coil that does not exist for the older platform. Second, when the service network for that generation is thinning: a system nobody can get parts for in three years is a system with a three-year life, whatever its condition today.
Both are answerable before you buy. Ask the manufacturer how long the platform will be supported for parts, and ask your own radiologists which capabilities on the current generation they would actually use. The second question usually produces a shorter list than the tender does.
