I am looking for a dataset listing MRI scanners in the United States with as many following fields as possible, ordered by descending importance:

  • Location
  • Number of teslas (as of now, commercial systems are available between 0.2T–7T, and sometimes even up to 10.5 Teslas (Siemens MAGNETOM 10.5T))
  • Whether it is publicly available (i.e., whether a patient can book an appointment)
  • Date when it was made available
  • Model name

I am mostly interested in the state of Massachusetts.

    spoke with close friend of mine who is a scientist and professor of medical physics for past ten years whose primary research technique is MRI -- he is unaware of any such dataset.

  • @BrandonLoudermilk Thanks! Well at least in the answer below we have 60% of the 7T MRI scanners, and 100% percent of the MRI scanners with over seven Testla :-) as usual maybe we should ask Google motherboard.vice.com/read/…

  • fyi - had no clue they made 10.5T scanners... wow.

  • @BrandonLoudermilk Yes, it's very exciting. e.g. some studies on the usefulness of MRI scanners with seven Testla and above health.stackexchange.com/q/5671/43 . My main clinical interest is tendinopathies.

I found this map showing the locations of Siemens MAGNETOM 7T, Siemens MAGNETOM 9.4T, Siemens MAGNETOM 10.5T, and Siemens MAGNETOM 11.7T in the world:

According to the website, it represents 65% of the 7T MRI scanners, and 100% percent of the MRI scanners with over seven Testla.

Magnetic-resonance.org

World­wide, there are approximately 36,000 MR machines. At present, about 2,500 MR imaging units are sold worldwide every year

  • This CDC link shows the amount per country.
