MRI can also be used to create a maps of the brain. It identifies regions of the brain that temporarily have increased cerebral blood flow during thought processes. These images are superimposed on standard MRI images. After these areas are defined, the neurosurgeon can use this information in pre-surgery planning.
A patient is placed in the scanner and asked to perform a task, such as raising an arm. This technique helps to identify the area of the brain responsible for that task and determine the safety of surgery in that area. The neurosurgeon can take this information and map out areas responsible for speech, movement, sensation and more.
FUNCTIONAL MRI BRAIN
During functional MRI, a patient is asked to perform a specific activity. The increased blood flow to the area of the brain that is responsible for that activity is highlighted on Functional MRI.
