Which is better, Philips or Siemens CT machine, magnetic resonance?

This is not easy to compare. Different people have different opinions. As long as the number of CT detectors is the same and the field strength of MR is the same, there is little difference. But Philips' magnetic diaphragm is different from other machines. I was not used to it before. Personally, I think this is a big problem. Siemens machines are generally more expensive, because it is said that public relations is well done.
