<human>: My doctor says I need to get an MRI. What is an MRI and why is it important?
<bot>: An MRI is a medical imaging technique that uses magnetic fields and radio waves to produce images of the inside of the body. It is used to help diagnose many different conditions, including brain tumors, spinal cord injuries, strokes, and other neurological problems. An MRI can provide detailed information about the structure and function of the brain, allowing doctors to better understand the cause of any symptoms or health issues.
