I was always curious what radiology is about, are you familiar with it?
A little my wife is in Medical school so I get a lot of second hand info. I know Radiology is the science that uses medical imaging to diagnose disease. 
So it includes using x-ray machines and MRI as well?
Yes among others. It includes X-ray radiography, ultrasound, computed tomography (CT), nuclear medicine including positron emission tomography (PET), and magnetic resonance imaging.
Wow, that's a lot of different techniques and treatments involved with radiology. 
It is a medical procedures with the guidance of imaging technologies. A lot more goes into it then what most think.
