Radiology, in its simplest explanation, is the ability to capture images of the inside of humans using electromagnetic and controlled nuclear radiation.
For thousands of years, humans have experienced various diseases and adverse health conditions which can display their effects through symptoms (i.e. a cough, a headache or sore stomach) or can even go completely unnoticed if asymptomatic before causing major health issues.
Prior to the invention of X-ray imaging in 1895, it was the role of anatomists to gain a greater understanding of the internal layout of the human body through dissections and drawings of their discoveries. This provided a better understanding of human anatomy, yet it was still highly risky to conduct surgery as surgeons weren’t able to view inside the patient to identify the cause (pathology) of the disease before the surgery.
