The nerve cells in our brain are continuously interacting to perform various activities. These activities range from simple tasks like holding an object with our hands to complex cognitive functions such as understanding spoken words. The brain also contains specialized regions for critical activities such as vision, hearing, touch, language, memory, and many others. Functional magnetic resonance imaging is a non-invasive, painless, and safe advanced diagnostic method that measures and maps brain activity.
Functional MRI is necessary when planning surgeries or radiation treatments after receiving a diagnosis like a tumor, to determine the boundaries of these treatments and assess possible losses. This helps protect important areas of the brain.
In order to interpret this imaging method, a static MRI taken previously is required. During functional MRI, increased blood flow is measured and mapped in the region of the brain related to the task in response to simple commands given.
