Which imaging method uses strong magnetic fields and radio waves?

Magnetic Resonance Imaging (MRI) utilizes strong magnetic fields and radio waves to generate detailed images of the organs and tissues within the body. The core principle of MRI is based on the alignment of hydrogen atoms, which are abundant in the body due to the high water content of tissues. When placed in a strong magnetic field, these hydrogen atoms align with the magnetic force. The application of radiofrequency pulses disturbs this alignment, causing the atoms to emit radio signals as they return to their original state. These signals are then processed by a computer to create high-resolution images, allowing for the examination of soft tissues, including the brain, muscles, and ligaments, which are often not as clearly visible with other imaging methods.

In contrast, Computed Tomography (CT) scans use X-rays to produce images; X-rays are a form of radiation that passes through the body and creates images based on tissue density. Ultrasound imaging employs high-frequency sound waves to visualize soft tissues and fluid-filled structures, relying on the echo of sound waves rather than magnetic fields. Standard X-ray images are generated using ionizing radiation, providing a different type of imaging without the use of magnetic fields or radio waves. Each of these methods has unique applications and advantages, but MRI
