Servicing vs. Remanufacturing: Where CT and MRI Work Falls
The FDA's framework, set out in its finalized remanufacturing guidance, draws a bright line that shapes imaging service. Servicing is repair and preventive or routine maintenance that returns a finished device to the OEM's original safety and performance specifications; remanufacturing is work that significantly changes those specifications or the device's intended use, and it triggers premarket, registration, and quality-system obligations.
For high-throughput CT and MRI systems, that distinction governs how upgrades, part substitutions, and software changes are handled. Keeping activity firmly on the servicing side โ restoring OEM specifications with documented calibration โ is what keeps a facility's program straightforward and its accreditation evidence clean under Joint Commission environment-of-care expectations.
The line matters most in the places imaging departments spend money. A tube swap using an OEM-specified assembly, a coil replacement, a calibration that restores published performance — all comfortably servicing. A third-party software modification that changes how a reconstruction behaves, a component substitution that alters the device's performance specification, or a change to the intended use are the sorts of activities the FDA's framework treats as remanufacturing, with the premarket, registration and quality-system obligations that follow. Knowing which side of that line a proposed job sits on before the purchase order is signed is worth more than knowing it afterwards.
There is a second, quieter reason to keep work firmly on the servicing side: your accreditation file. Imaging performance is independently measured — through ACR accreditation phantom studies and the annual medical-physicist survey — and a system that has been altered in undocumented ways is a system whose physics report becomes very hard to interpret. Restoring to published specification, and writing down exactly what was restored and how it was verified, keeps the physicist, the surveyor and the radiologist telling the same story about the same scanner.
