Radiology is a branch of medicine that uses imaging technology to diagnose and treat injuries and diseases. The origins of this field of medicine date back to the end of the 19th century, when Wilhelm Rontgen discovered X-rays in 1895; a discovery that would bring him the Nobel Prize in Physics in 1901.

From its very inception, radiology has had huge potential for improving health.

A radiologist is a doctor who specializes in the diagnosis and treatment of diseases and injuries using medical imaging techniques. Some of these imaging techniques involve the use of radiation and require training in understanding the safety and security practices in the field of radiology. From X-rays to magnetic resonance imaging (MRI), radiology is of great importance for health, from both the diagnostic and therapeutic aspect.

Today radiology includes various techniques in addition to X-rays, such as ultrasound, Doppler ultrasound, CT scan and magnetic resonance imaging.
