Magnetic resonance imaging (MRI) of the brain is a safe and painless test that uses a magnetic field and radio waves to produce detailed images of the brain and the brain stem. An MRI differs from a CAT scan (also called a CT scan or a computed axial tomography scan) because it does not use radiation.
Is MRI scan scary?
This is not because MRI scans are dangerous, or even particularly scary. It is just an unusual experience in which our natural and normal reaction is to be at least a little cautious of what is happening around us.

How long does it take for an MRI to be done?
A magnetic resonance imaging (MRI) scan is a painless procedure that lasts 15 to 90 minutes, depending on the size of the area being scanned and the number of images being taken.
