Magnetic resonance imaging (MRI) primarily utilizes radio waves and magnetic fields to create detailed images of the organs and tissues within the body. When a patient is placed inside the MRI machine, the strong magnetic field aligns the hydrogen atoms in the body. Subsequently, radio waves are sent through the body, disrupting this alignment. When the radio waves are turned off, the hydrogen atoms return to their original alignment, releasing energy in the process. This energy is detected by the MRI scanner and is then processed to create images that provide valuable information regarding the structure and function of the body.

Understanding why MRI uses this technology is essential, as it allows for comprehensive imaging without the exposure to ionizing radiation associated with techniques like X-rays or computed tomography. This distinction highlights the safety and advantages of MRI in various clinical settings, especially for soft tissue evaluation, such as the heart and brain.
