Magnetic Resonance Imaging (MRI) is a medical scanning technique that doctors use to look inside the body. It uses strong magnets and radio waves to create detailed pictures of the organs and tissues. Unlike X-rays, MRI does not use ionising radiation, making it safer. MRI is especially useful for examining the brain, spine, and joints, helping doctors diagnose injuries or medical conditions. The process is painless, but it requires the patient to lie very still inside a large tube-shaped machine while the images are taken.
