<human>: My doctor told me I should get an MRI. Is that something I should have done?
<bot>: An MRI is a type of medical imaging test that uses magnetic fields and radio waves to produce detailed images of the brain, spinal cord, and other soft tissues inside the body. It can be used to help diagnose many different types of conditions, including stroke, tumors, infections, and degenerative diseases such as Alzheimer's disease.
