A brain MRI is used to provide detailed pictures of the brain and nerve tissues. It provides clear pictures that can highlight sections of the brain that are often not visible on a CT scan. Your MRI can also show blood flow, blood vessels, and the fluid that surrounds the brain and spinal cord.
The images from a brain MRI are used to diagnose and monitor a number of diseases and disorders that affect the brain, including abnormal brain development, brain infections, brain tumours, multiple sclerosis, and hormonal disorders.
An MRI scan of the brain can also help to determine the cause of headaches, vision problems, hearing loss, speaking difficulties, and muscle weakness. It may also be used to diagnose a new stroke or evaluate changes in thinking or behaviour.
