MRI machines are advanced medical devices that use strong magnetic fields and radio waves to create detailed images of the organs and tissues inside the body. They are particularly useful for diagnosing conditions related to the brain, spine, and joints, providing a non-invasive way to visualize internal structures without the use of ionizing radiation. During an MRI scan, patients lie on a movable table that slides into a large, cylindrical machine. The process is painless, although some may feel claustrophobic due to the enclosed space. MRI machines are essential tools in modern medicine, aiding in accurate diagnosis and treatment planning.
