response: I have no idea!  Oh another technique they use for imaging is the PET.  That stands for positron emission tomography, and it's a type of nuclear medicine.
original_response: I go to regular medical school to learn how to use PET and CT as well as MRI.
history: I don't know much about radiology, but one of my cousins is a radiologist. It must take a lot of studying to qualify to do that job. Hmm I don't know what education is needed for that.   I do know that by using imaging, diseases can be diagnosed and sometimes treated.  Radiology is a science! You mean like x-rays? I've had plenty of those - broken hip. Well there are a variety of imaging techniques, and one is x-ray. What other forms of imaging techniques does a radiologist use? They also use ultrasound and CT. Oh, ok. I've had a CT, but not an ultrasound, I don't think. How long do you have to study in order to qualify? I'm not sure, but also CT stands for computed tomography. I didn't know that. Is there a special Radiology school, or do you go to regular medical school?
knowledge: 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 and/or treat diseases.
