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?
Radiology
Radiology is the medical specialty that uses medical imaging to diagnose and treat diseases within the human body.
A variety of imaging techniques such as X-ray radiography, ultrasound, computed tomography (CT), nuclear medicine including positron emission tomography (PET), and magnetic resonance imaging (MRI) are used to diagnose or treat diseases. Interventional radiology is the performance of usually minimally invasive medical procedures with the guidance of imaging technologies such as X-ray radiography, ultrasound, computed tomography (CT), nuclear
Fluoroscopy
Fluoroscopy () is an imaging technique that uses X-rays to obtain real-time moving images of the interior of an object. In its primary application of medical imaging, a fluoroscope () allows a physician to see the internal structure and function of a patient, so that the pumping action of the heart or the motion of swallowing, for example, can be watched. This is useful for both diagnosis and therapy and occurs in general radiology, interventional radiology, and image-guided surgery. In its
