My doctor told me I need to get an MRI. What is it and what should I expect?

An MRI (Magnetic Resonance Imaging) scan uses magnetic fields and radio waves to produce images of the body. It is a non-invasive diagnostic procedure that provides detailed information about the structure, function, and pathology of the brain, spinal cord, and other organs. The MRI scanner produces images by detecting the hydrogen atoms in water molecules in the body.
