Brands of Scanners

How many brands of scanners are there?  
If you can only name a handful of the largest MR vendors (GE, Siemens, Philips, etc) you may be surprised to learn that at least 23 different companies currently manufacture and sell MR scanners for human diagnostic use that are FDA-approved in the United States.  These companies, together with model names and scanner types, are listed below. For completeness I have included some models that are no longer in production but which still have an installed base or can be purchased refurbished from independent dealers.  A number of the smaller/newer companies manufacture and sell their devices primarily in Asia. Interested readers should check each manufacturer's web site for the most up-to-date product information.  

I have chosen not to include the names of companies producing research only or veterinary scanners. Likewise, I have omitted the names of many great companies (such as Technicare, Picker/Marconi, Instrumentarium, Elscint, Shimadzu, ONI) that historically manufactured MR scanners but are either no longer in business or have been acquired by others.  In the last 3 years, Hitachi has been acquired by 
FUJIFILM and Toshiba by Canon.

All scanners in the list below contain superconducting magnets unless specifically designated as permanent (P) or resistive (R).  Discontinued models are listed in green.
