My doctor told me I should get an MRI. Is that something I should have done?

It’s a good idea to consult with your doctor before scheduling any medical tests, and it can help you understand what they involve and how they are used. An MRI is a type of scan that uses magnetic fields and radio waves to create images of the brain, so it can provide useful information about potential health problems. However, it is not always necessary for every situation.
