You've got a long way to go. 🙂
The short answer is not to worry about radiology for a while. Focus your efforts on choosing the right college for you, and doing your best to excel. Getting into medical school is typically independent of your major (discussed ad nauseam in the pre-allo forum, do a search), and if you're anything like the rest of us, you're going to change your career goals about 10 times in college, and another 10 times in medical school.
But just so you know, the pathway to becoming a radiologist is:
4 years college
4 years medical school
1 year internship (typically medicine or transitional year)
4 years residency
+/- 1-2 years fellowship (e.g. MRI, neuroradiology)
Enjoy the rest of your senior year, and remember to keep an open mind when you get to college. Who knows... maybe you're cut out to be a radiologist, or maybe you'll end up doing something completely different.
