i'm a d.o. who will be applying to allo rads. it is possible to do it-but you must bust ***** during med school. Here's what to do if you haven't started med school already or are just starting.
1) Get good grades-try to be at least in the top quarter of your class.
2) Get some research experience, if it's not in radiology its okay, research is research and if you can publish than all the better.
3) Do very well on Step 1. Shoot for 235+ if not 240+.
4) Kiss a lotta radiologist ***** during 3rd year and get LOR
5) Honor as many clerkships as possible.
6) Take Step II, again shoot for 235+ if not 240+. Many people say that if you have a good Step I, than don't take step II. Being an osteopath, a good step II will help your application quite a bit. If you did well in Step I, chances are you'll do well on Step II if you put in the work. So why be lazy, when a good step II will enhance your chances of matching?
7)Apply broadly because it will only enhance your chances of getting more interviews.
Do all this, and you're in great shape of matching into a respectable radiology program. It's very tough to get into as it is, and being osteopath doesn't help, but if you are able to do the above, then the odds will be in your favor...
Good luck to you.
