MRI
A Magnetic resonance imaging is used to detect any sort of diseased area in the brain. The procedure does not involve any sort of operative or invasive process. However, a sedative might be given to the patients in order for them to stay calm during the process. There are no possible side effects of an MRI because it uses a magnetic field and radio waves. If you are wearing any sort of metal you will be advised to take it off before an MRI.
