WebMagnetic Resonance Imaging (MRI) is a groundbreaking non-ionising imaging modality that revolutionised the field of diagnostic medicine. Developed in the 1970s, MRI uses a combination of powerful magnetic fields, radiofrequency pulses, and sophisticated computer algorithms to generate detailed images of the body’s internal structures. Ionizing radiation is used in a wide variety of fields such as medicine, nuclear power, research, and industrial manufacturing, but presents a health hazard if proper measures against excessive exposure are not taken. Exposure to ionizing radiation causes cell damage to living tissue and organ damage.
