Im studying radiology in school, radiology is the science that uses medical imaging to diagnose people.
That's interesting. What kinds of medical imaging do you study?
Well I want to do Interventional radiology it used to treat and image patients. 
That would be a fascinating job. I've never had an x-ray before, but the images look really cool.
It is fun sometimes,  In some places, a Reporting Radiographer is called in. They are pretty much a expert radiographer.
Do radiographers also do things like fMRI scans? Or is it just x-rays?
They use a lot of stuff A variety of imaging techniques such as X-ray radiography, ultrasound, computed tomography (CT), nuclear medicine including positron emission tomography. And thats just to name a few!
Wow, that sounds like a lot to learn. Hopefully I'll never need any of that stuff!!
