Checklist for Buying a Used MRI Scanner

Why the checklist matters

An MRI is not a single machine. It is a superconducting magnet, a gradient chain, an RF chain, a cooling system, a computing platform and a set of software licences — each of which can be in a different condition and each of which can be quoted separately or not at all. Two adverts for the same model and field strength can describe systems whose real cost differs by six figures.

The twelve points below are the ones that most often change the price, the timeline or the feasibility of a purchase. Work through them before agreeing a figure, not after.

1. Field strength, bore and magnet state

Field strength (1.5 T or 3 T for most clinical work) and bore diameter (typically 60 cm, or 70 cm on wide-bore platforms) determine clinical scope and patient comfort. But the decisive commercial variable is the state of the magnet.

Magnet state	What it means	Commercial effect
Cold and at field	Superconducting, energised, cryogens topped up	Highest price. Must be ramped down before transport, but the coil integrity is proven.
Cold, ramped down	Still cold, field removed in a controlled ramp	Normal condition for a transported magnet. Requires ramp-up and shimming at destination.
Warm	Cryogens gone, magnet at ambient temperature	Lowest price. Requires cool-down, helium fill and recommissioning — a substantial, quotable cost with residual technical risk.
Quenched	Uncontrolled loss of superconductivity	Needs investigation. A quench is often harmless, but the cause must be understood before purchase.

Ask for the magnet state in writing, with the date it was recorded, and ask who is responsible for the cost if the state turns out differently on inspection.

2. Coil configuration

Coils are where used-MRI deals most often go wrong. A system advertised at an attractive price may include only a head coil and a spine coil built into the table. Replacing a missing body, shoulder, knee or breast coil can add tens of thousands to the total.

Request a written coil list with part numbers and quantities, and confirm that every coil is included in the sale, physically present at the site, and functional. Coils are also the most common item to be quietly removed between inspection and deinstallation — list them in the contract.

3. Software version and licences

Note the operating platform and software release (for example a Siemens syngo MR release under NUMARIS, or the equivalent on GE, Philips or Canon platforms). Two questions matter:

• Which application packages are licensed? Diffusion, spectroscopy, cardiac, MR angiography, breast, advanced neuro and similar options are licensed individually. An unlicensed option is not a feature.
• Is the licence transferable? Licences are usually tied to the system serial number, but manufacturer policy on transfer to a new owner and new site varies. Confirm before assuming.

Also check whether the release is still supported and whether an upgrade path exists — an unsupported version limits future service options and can complicate cybersecurity compliance in hospital networks.

4. Gradient and RF chain

The gradient amplifier, gradient coil, RF amplifier and body coil are high-value assemblies. Ask for the gradient configuration by name (manufacturers use specific designations for gradient strength and slew rate), and confirm that gradient and RF amplifiers are included, not cannibalised for another site.

5. Cooling: chiller, cold head and compressor

A cold head has a service life measured in operating hours and is a normal replacement item; a compressor is a serviceable unit; a chiller is often site infrastructure rather than part of the system. Establish for each whether it is included, its age, and its last service date. If the chiller belongs to the building, budget for one at the destination.

6. Helium history

Ask for the helium level trend and refill history. A magnet with an unusually high boil-off rate signals a problem with the cryostat or the cold head, and helium is a significant recurring cost. On a healthy modern zero-boil-off system, refills should be rare.

7. Logs, error history and utilisation

Service logs and system error logs are the closest thing to an honest biography of the machine. Request:

• The service history, including major component replacements
• Recent system error logs
• Approximate patient throughput or operating hours
• The date of the last preventive maintenance visit and by whom

A system with a full service history under a manufacturer or reputable third-party contract is worth more than one without, and the difference is usually smaller than the risk it removes.

8. Independent technical inspection

Arrange an inspection by an engineer who is not the seller, ideally while the system is still installed and operational. A pre-purchase inspection should cover image quality and phantom testing where possible, coil verification, console and workstation operation, visible condition of covers, table and cabinets, and a review of the logs. Photographs should include the gantry, bore, table, coils, cabinets, console and the system label showing model and serial number.

9. Deinstallation, rigging and transport

Deinstallation is a project in itself. Confirm who pays for ramp-down and cryogen handling, rigging, any wall or roof opening, making good the building afterwards, crating and transport. Confirm the rigging route out of the building before agreeing a price — an inaccessible magnet is a very expensive surprise. See the MRI deinstallation and transport guide for the full sequence.

10. Fit with the destination room

Check the destination room against the manufacturer's site planning guide for that model: room dimensions, door and corridor access, floor loading, quench pipe route, HVAC capacity, electrical supply and the position of the 5 gauss line relative to occupied areas. A system that does not fit the room is not a bargain. See preparing a room for MRI installation.

11. Documentation and regulatory status

Ask for the system label photograph, serial number, year of manufacture, CE marking evidence where applicable, and the refurbishment documentation if the system is sold as refurbished. Requirements at the destination vary — some countries restrict the import of used medical devices above a certain age or require registration before customs clearance. See importing refurbished imaging equipment.

12. Total cost of ownership, not headline price

Build the real number before comparing offers. A realistic budget includes the equipment price, deinstallation and rigging, transport and insurance, import duties and clearance, RF shielding and room works, installation and commissioning, ramp-up and helium fill, applications training, and the first year of service cover. On a warm magnet, recommissioning alone can change the ranking of two offers.

Quick summary

• Get the magnet state in writing, with a date
• Get a coil list with part numbers, and put it in the contract
• Confirm which software options are licensed and whether they transfer
• Read the service and error logs before negotiating
• Inspect with your own engineer while the system is still running
• Confirm the rigging route out and the room fit in
• Compare total cost of ownership, not headline price
