Could neutrons be used instead of X-rays for medical imaging? Would that be safer?

I know that X-rays are more commonly used because they're easier to produce, but if we could produce neutrons without the use of a nuclear reactor, would it be possible to use neutrons  for medical imaging? And would that be safer?

Neutrons can transmute nuclei, making them radioactive. That would not be very good when you're dealing with a human body.

Also since neutrons are not charged, we can't really control how fast they move.
