What is radiology about?
Radiology is a medical science that uses imaging to diagnose diseases in the human body
Ok what does it take to become a radiographer?
I'm pretty sure it requires a post-secondary degree. They are healthcare professionals
What equipments do they use?
Not sure, but I know they are erroneously referred to as "x-ray technicians"
When was the practice first used?
I don't know, but I did discover they use CT machines, PET machines and MRI's
Thanks for enlightening me about Radiology
