Very uninformed take, its almost laughable.
GE isn't the only one who makes MRIs. The other big players are Siemens, Philips, United, and to some extent Canon, Fujifoto, and Hitachi.
No, that's really how much it costs. The margin on MRI machines is terrible. I'd like to see you do it cheaper... "Just" build then supercool magnet for superconduction for 3T of homogenius magnetic field, build coils that handle KW of RF/gradients that can fit a human comfortably without artifacts, build the high power and precision circuitry to transmit and receive said RF, then control that equipment accurately and safely.
Super easy, off-the-shelf stuff.
Oh, and you can't use any ferrous parts, nor can your power supplies generate any noise.
That's like, senior design level stuff amirite
The other big factor in cost is supply chain. Everything has to be tracable. So the supply chains have to do a lot of paperwork, inspection audits, since a defective part can kill someone.
