[Intl_DxMedPhys] Helium free MRI

[Bob Kobistek]

Not the answer to your question, but I remember that Toshiba once had an open MRI scanner called the Opart, which had helium-free superconducting magnets. The big downside was that if the cold head went down, the magnet would quench in minutes.

Hi all, I heard there is an expectation to major shift to helium free MRIs after 2026. I do not know much about the price/performance values and clinical practice of helium free MRIs, especially in comparison to helium cooled MRIs. Anybody can
Hi all,

I heard there is an expectation to major shift to helium free MRIs after 2026.

I do not know much about the price/performance values and clinical practice of helium free MRIs, especially in comparison to helium cooled MRIs.

Anybody can share some sources for this information?

Thank you,
Lei
