<p>I just did a paper on Radiology and Anesthesiology, and they pay really well(if thats what your shooting for, but i would hope there is more intrigue in the Medical field then just money for you), but there is also a intensive Residency. For anesthesiology atleast where i live(Wisconsin) you need 6-8 years of residency. Im sure radiology isn;t quite as long, but for any field your going to be spending some time on it. Good luck with what you decide</p>
