a non-invasive medical imaging technique that uses powerful magnetic fields and radio waves to produce detailed pictures of the inside of the body. Unlike X-rays or CT scans, MRI does not expose patients to ionizing radiation. The strong magnetic field temporarily affects the alignment of hydrogen atoms in the body. When these atoms return to their original positions, they emit signals that are detected by the scanner and processed by a computer to create high-resolution images of tissues and organs. MRI can be used to visualize nearly all types of body tissue, making it an essential tool in modern diagnostics.
