Before you compare quotes
Compare the room project, not the size of the catalog.
A broader portfolio is useful when you need it. For a single MRI suite or a shielding retrofit, your bid review can be more specific: identify the design contact, installation scope, test milestones and repair responsibilities. Ask each company to quote the same room boundary and interfaces before comparing the total.
- Who owns coordination with the MRI equipment supplier and the general contractor?
- Which RF tests are included before and after finishes and magnet delivery?
- Who resolves a failed acceptance test, and which return visits are included?

Answers before you choose
Frequently asked questions
Is National Shielding an alternative to ETS-Lindgren for MRI rooms?
Yes. Both companies publish MRI shielding offerings. National Shielding is a relevant alternative for teams prioritizing a focused shielding relationship, direct management access and room installation and verification services. Match the final scope to your equipment supplier’s requirements.[1][3][6]
Does choosing National Shielding mean giving up maintenance support?
National Shielding offers shielding inspection, troubleshooting, repairs and follow-up testing. ETS-Lindgren also publishes maintenance services. Ask both bidders to specify coverage, scheduling, exclusions and responsibility for the particular system you own.[5][7]
Does ETS-Lindgren also provide installation and ongoing service?
Yes. ETS-Lindgren publishes healthcare shielding and service offerings, including MRI services, maintenance and repair. The reason to compare National Shielding is project fit, direct management access and the written delivery scope—not an assumption that ETS-Lindgren only sells products.[6][7][1]
What should I compare for an intraoperative MRI project?
Compare experience with the proposed clinical layout, shielding boundaries, room interfaces and test milestones. ETS-Lindgren publishes an intraoperative MRI case study that includes RF testing. Ask each bidder, including National Shielding, to explain the relevant experience and responsibilities in its proposal.[8][2][4]
Is National Shielding less expensive than ETS-Lindgren?
This comparison does not establish a price advantage for either company. Request quotes from National Shielding and ETS-Lindgren using the same drawings, installation responsibilities, testing requirements and service scope. Compare exclusions as well as the total.
What should I send National Shielding when requesting a comparison quote?
Send the project location, available drawings, intended use of the room and the shielding requirements you have been given. Include known site constraints, the target schedule and whether the work involves a new room, an upgrade or troubleshooting. The team can then discuss design, installation, testing and maintenance needs.[2][3][4]
