Functional MR (f-MR)
Functional MR (f-MR) is a non-invasive imaging study that involves the
measurement of dynamic blood oxygen level-dependent signal parameters
within the brain. f-MR illustrates how the brain thinks and initiates
activities by monitoring brain activity as the patient is asked to perform
tasks such as finger tapping or recitation of number sequences.
These activities cause changes in chemical composition of involved areas
of the brain. f-MR produces images of the involved areas of the brain,
pinpointing abnormalities and identifying important areas of the brain
that control movement, speech and senses—areas to be avoided during
surgery. f-MR is also used to acquire real-time, 3D information of the
brain that is used in conjunction with Hoag’s Gamma Knife and stereotactic
Advanced Neuroimaging Techniques here.
