Radiology?

<p>I was looking through some medical fields and I came across radiology. This career seems interesting and I've always liked technology, as well as had an interest in the medical field. However, I am not exactly sure of what a radiologist does besides x-rays and MRI's, etc.</p>

<p>Could someone point me in a direction of which colleges I should look at to study this field, how long it'll take me to finish, and any links would be helpful!
Much thanks</p>
