Radiologist in Private Practice ?

As a radiologist, can you open a private practice or group practice (by this I mean, by having a private practice, there's no max for earning potential such as salary, but you could work as much as you want and sky is the limit for earning potential)? Also, does radiology require a lot of analytical thinking more than surgery fields? Which field in medicine would require analytical thinking most?

I don't think there is much analytical thinking required in radiology. The idea of private practice is cool though.

No, As far as I know..you are not allowed to practice alone.you HAVE to have a team to do radiology..
