How Long Does It Take to Purchase and Install a Used MRI Machine?

Updated 28 September 2026.

A typical refurbished MRI project runs 8 to 16 weeks from the signed contract to the first patient scan. That range comes from the Amber Diagnostics MRI Site Planning Guide. Site preparation fills most of those weeks. The magnet rarely sets the date. The room does.

Quick Answer

• A representative outpatient 1.5T refurbished project takes 8 to 16 weeks from the signed contract to the first patient scan.
• After the room is ready, the physical install takes 2 to 4 weeks. That window covers delivery, cryogen fill, shimming, and calibration.
• The room is the critical path. Permits, the RF shielded enclosure, electrical service, and the quench pipe route set the date.
• A new suite or a heavy renovation uses a different clock. Construction alone can take 6 to 12 months.
• The Amber Diagnostics buy-used page uses a longer clock: 90 to 180 days from the first call, not from the contract.
• A mobile MRI rental can hold scan volume while the fixed room is offline. Planned delivery takes 2 to 4 weeks after contract if a unit and a pad are ready.

How long does a used MRI purchase and install take?

A representative outpatient 1.5T refurbished project takes 8 to 16 weeks from the signed contract to the first patient scan. Site preparation fills most of that time. The physical install takes 2 to 4 weeks after the room passes the pre-install shield test. Permits, long-lead parts, and unit availability move the date.

Two Amber Diagnostics figures look like a clash until you check the start point. The site planning guide counts 8 to 16 weeks from the signed contract. The buy used MRI machine guide tells buyers to plan 90 to 180 days from the first call. The first-call clock includes the search, the inspection, quotes, and internal approval. The contract clock does not.

Neither range covers a shell space with no permit file. Start with the MRI buyer's guide. Then review current 1.5T MRI systems. Amber Diagnostics quotes a timeline after the site survey. The published ranges are planning figures, not a promised date.

What are the stages from purchase to first scan?

A used MRI purchase moves through seven stages. The stages overlap. Site work runs in parallel with sourcing and the seller de-install when your facility starts drawings in week 1. A facility that waits for the magnet to ship before it calls a contractor loses that parallel time.

The guide gives this week path for a representative outpatient 1.5T project. Weeks 1 to 2 cover the site survey, drawings, the permit application, and contractor selection. Weeks 2 to 4 cover demolition or structural work, plus orders for RF shield panels, the quench pipe, HVAC equipment, and the chiller.

Weeks 4 to 6 cover the RF shielded enclosure, electrical rough-in, HVAC rough-in, chilled water piping, and the quench pipe. The room is ready for delivery after the shield passes the pre-install test. Weeks 6 to 8 cover the rigger walk, delivery, rigging, ramp-up, cryogen fill, cabinet connection, and the post-install shield test.

Weeks 8 to 10 cover calibration, coil tests, software validation, and phantom imaging. Add ACR phantom scans in that window if your facility needs them. Weeks 10 to 12 cover applications training, PACS and worklist integration, and the medical physicist inspection. The first patient scan starts in week 12 or later.

Two details inside that path cause more lost weeks than a late magnet. The cold head must stay powered through de-install, transport, and any wait before install. Loss of cold-head power lets the magnet warm. A boiled-off magnet needs a re-cool and a helium fill. That work adds weeks.

The rigger must walk the full delivery route at least 4 to 6 weeks before delivery. That walk finds a tight hallway while a drawing change still fixes it. The same hallway on delivery day forces a new date. In that same early block, ask for service history, the coil list, and the software version. Use the buy used MRI machine guide as the checklist.

How long does it take to install a refurbished MRI?

The physical install takes 2 to 4 weeks after the room is ready. That figure comes from the Amber Diagnostics MRI FAQ. On the representative path, calibration through the first patient scan sits in weeks 8 to 12. The crew needs a finished shield, live power, working HVAC, and a clear access path on day one.

The crew rigs the magnet into place, connects the cabinets, and completes ramp-up and the cryogen fill. Shimming comes next. Coil checks and software validation follow. The shield gets a second test after install. The first test does not cover penetrations the crew opens later.

Applications training typically runs 3 to 5 days on site. That block sits inside weeks 10 to 12, next to the PACS and worklist test. It is a training window, not a second install.

A warm magnet is not a one-day fix. A lost cold head is the same problem. The re-cool and the helium fill add weeks, and every later milestone moves with them. Put helium and cold-head duty in the contract before the truck leaves the seller site. The five questions before you buy a used MRI cover that talk.

What most often delays an MRI installation?

Permits, RF shield lead time, electrical service, the chiller, the quench pipe route, and the access path delay more projects than the magnet. Those items sit in the room, not in the scanner. The rigger walk is the check that finds a tight hallway, a short door, or a weak floor while a drawing change still fixes it.

An MRI needs an RF shield. That shield is a Faraday cage, not a lead radiation room. Plan HVAC, floor load, the quench pipe path to the exterior, and emergency power in the same package. The 5-gauss line must stay inside a controlled area. The guide lists a planning minimum of about 22 by 25 feet clear of shielding for most 1.5T systems. That figure is a planning minimum. It is not a fit for every model.

The Amber Diagnostics MRI Site Planning Guide lists a dedicated 480V or 208V three-phase service for fixed high-field systems. Continuous load is about 50 to 80 kVA for a 1.5T system and about 90 to 150 kVA for a 3T system. The guide gives no single amp figure for every fixed magnet. The Amber Diagnostics Mobile MRI FAQ states that many mobile MRI trailers use 480V, three-phase, 150A service. A specific Siemens MAGNETOM Aera mobile unit in the Amber Diagnostics unit files needs 480V, three-phase, 200A service and a Russell Stoll connector. Use the OEM siting document for the selected system. Do not copy one magnet's power figure onto another.

A late room does not stop patient scans when a mobile unit is on site. A mobile MRI rental bridges the gap between removal of the old scanner and install of the next one. Planned delivery takes 2 to 4 weeks after contract when a unit is available and the pad is ready. In emergency cases, Amber Diagnostics placed units in 7 to 14 days after contract when a fixed scanner was down. That speed depends on a staged unit. Do not treat it as a standard date.

A mobile unit still needs power, a level pad, and local permits. Your facility supplies the pad, the electrical work, and the permits. The base rental rate does not include a technologist.

How does financing timing fit the purchase schedule?

Get lender approval before you book the de-installation. An unfunded file can miss the seller de-install window. A missed window moves the ship date to the next open week on the seller calendar.

The Amber Diagnostics MRI FAQ lists four common paths: equipment loans, operating leases, capital leases, and vendor payment plans. Many vendors offer deferred payment programs with no payments for 6 to 12 months during installation and ramp-up. That pattern is not a term on every Amber Diagnostics deal. Confirm the payment schedule in the agreement before the crew books the de-install. US customers can ask Amber Diagnostics about financing.

Fund the whole project, not only the scanner line. Site work, rigging, physicist time, and training sit on the same calendar. A buyer who funds only the magnet stalls when the contractor asks for the shield deposit. Align the first payment with the projected first patient scan when the agreement allows it.

How Amber Diagnostics helps with the timeline

Amber Diagnostics started in 1994 and works from Orlando, Florida. The company sells, refurbishes, and rents used imaging equipment. The project team walks your site and builds a timeline from the first site survey through the first patient scan. The team gives drawings to your contractor early, so the shield vendor and the electrician work from the same plan.

The same team handles shipping, installation, and technical servicing. One plan holds the ship date and the room date. If the fixed room is offline, a mobile MRI rental can hold scan volume until the new system passes acceptance. Compare 1.5T MRI systems and 3.0T MRI systems for selection. Do not assume a listed model is in stock on the day you call. Ask which system fits the delivery window.

Request a project timeline for your site. Send room dimensions, ceiling height, the electrical service you have now, and the target first-scan date. The team builds the schedule from those facts.

FAQ

How long does it take to install a used MRI?

The physical install takes 2 to 4 weeks after the room is ready. That window covers delivery, cryogen fill, shimming, and calibration. The full contract-to-scan range for a representative refurbished 1.5T project is 8 to 16 weeks, because site preparation takes most of the time.

What delays an MRI installation?

Permits, RF shield lead time, electrical service, the chiller, the quench pipe route, and the access path cause more delay than the magnet. A lost cold head is the costly one. A warm magnet needs a re-cool and a helium fill. The rigger walk, at least 4 to 6 weeks before delivery, finds access problems while a drawing change still fixes them.

Can I scan patients before ACR accreditation is complete?

Install day and accredited status are not the same event. ACR revised the testing overview on 17 April 2026. The overview states that an MR unit must pass clinical image tests and phantom image tests. The work involves the lead supervising physician, the MR technologist, and a qualified medical physicist. Phantom imaging and the physicist inspection come before the first patient scan in the Amber Diagnostics timeline. The ACR submission packet is a separate facility process. See the ACR MR testing overview.

Can a mobile MRI rental cover the gap?

Yes. A mobile rental bridges removal of the old scanner and install of the next one. Planned delivery takes 2 to 4 weeks after contract when a unit is available and the pad is ready. Your facility supplies the pad, the electrical work, and the local permits. The base rate does not include a technologist.

When do I lock financing?

Lock financing before you book de-installation at the seller site. A late approval can cost the seller de-install slot and the ship date tied to it. Confirm the payment schedule in the agreement first. Align the first payment with the projected first patient scan when the agreement allows it.
