MRI of the brain is one of the modern non-contact methods of brain research, which uses a magnetic field and radio waves that transmit a signal to a computer and allow you to assess the state of the brain. It is important to know that MRI of the brain is used to examine both soft tissues and blood vessels for damage or injury, such as a stroke.
