Used MRI Scanner

Used MRI Systems

ROS' knowledgeable sales and project management team will work with you from the onset to ensure your refurbished MRI exceeds your expectations. From equipment selection, to post installation parts and maintenance support, we give you the peace-of-mind you deserve to implement your project.

Buying a used MRI

Buying an MRI takes careful planning in order to effectively implement a successful project. There are four main factors to consider when deciding to purchase a new or used MRI scanner. 

Clinical Objectives Site Planning Project Timeline Budget Successful

Identifying each of the four factors in advance will go a long way to ensuring your project is a success. Our goal at ROS is to provide you with guidance in selecting the optimal MRI that meets your goals as defined by the four factors.


Clinical Objectives

Clinical Objectives

Today, MRI is the modality of choice for a number of neurological and musculoskeletal applications.  MRI is supplementing existing techniques, such as vascular and cardiac imaging, while in others it is used to image physiologic processes that are invisible to any other imaging modality. MRI scanners are growing increasingly complex. As the technology develops, capabilities that were once available only to researchers are becoming routine in clinical applications. As a result, buyers now have more decisions to make when selecting a scanner than ever before. It is no longer simply a choice of field strength or whether to opt for an open or closed system. You must know what type of studies you plan to perform and which MRI capabilities you need in order to optimize your results for each study.

Site Planning

Site Planning

With regards to MRI, the site planning step is quite possibly the most important step in implementing a new or refurbished system.  With the sensitivity of the magnetic field to ferro-magnetic  materials, one must analyze every possible angle around the field.  From chillers to soil samples, understanding the impact will greatly increase the chance of a successful implementation. See our MRI site planning checklist below for a more detailed list of items to consider when planning for an installation. MRI Site Planning Checklist

Project Timeline

Project Timeline

When establishing your project timeline, be aware of the key milestones to maintain your project completion date. Key milestones include: site plan, equipment selection, availability of equipment, refurbishment work, room renovation requirements, installation time and clinical applications training.  Most of these milestones are interrelated and a delay in any of them will impact the completion of your project.  Make sure to build in flexibility, but also make sure you have a team that is committed to ensuring the completion of your project within your timeframe.



Buying a refurbished MRI system already reduces your budget requirements. After considering your clinical goals and your timeline, you should develop a budget for your equipment acquisition. The prices vary greatly depending on the age of equipment, technology and manufacturer. Be sure to allocate for other products and services you will require to operate your practice such as patient positioning devices, consumables, equipment commissions, and staff training.

MRI Site Planning Checklist

The following list summarizes the most important topics to be considered in designating an MR imaging facility. The list of functional areas can be used as the basis for estimating the area necessary once the functional requirements of a particular site are known.

Primary MRI Areas
 o Scan Room
 o Control Room
 o Computer Equipment Room (includes RF equipment and power supplies)
 o Reading Room (include physician’s console)
 o Cryogen Storage
Secondary MRI Areas
 o Film Processing (if required)
 o Quality Control and Service
 o Patient Preparation, Recover and Emergency Procedure Area
 o Patient Reception and Waiting Area
 o Storage
 o Washrooms
 o Soiled Utility
 o Clean Utility
Ancillary MRI Areas (These areas can be remote from the MRI or shared with other services)
 o Administrative Area
 o Conference Area
 o Additional Storage
 o Offices
Construction and Access Considerations
 o Equipment transportation, unloading and installation access
 o Floor loading
 o Floor levelness
 o Ceiling heights
 o Access for cryogens
 o Cryogen venting (normal and quench)
 o Controlled access to facility and well controlled access to magnet room
Protecting Magnetic Field Homogeneity
 o Location and amount of steel shielding
 o Other structural iron and steel
 o Large ferrous structures or objects
 o Symmetrical location of ferrous structures
 o Moving ferrous objects (elevators, lift trucks, vehicular traffic, etc.)
Protecting Surrounding Environment from Magnetic Fields
 o A 3-D survey of magnetically sensitive devices and equipment
 o Tolerable distances from the center of the magnet will depend on magnet field
    strength and shielding design
Radiofrequency Shielding
 o Design appropriate RF shielding based on a site survey according to the OEM 
 o Avoid light dimmers and fluorescent lighting ballasts within the magnet room
Facility Environment
 o Electrical supplies (voltages, current and phases)
 o Air conditioning (general area, computer room with temperature, humidity
    and filtration)
 o Water supply and floor drains (includes sink for phantom filling and draining)
 o Chilled water supply (temperature, flow rate and tolerable temperature fluctuation)
 o Personnel protection (establish controlled areas and metal detection routines
 o Fire Detection and Safety (no sprinklers, non-ferrous extinguishers)
 o Housekeeping (no ferrous cleaning tools or supplies)
