WebAug 1, 2014 · A form of MRI known as functional MRI (fMRI) has emerged as the most prominent neuroimaging technology over the last two decades. fMRI tracks changes in blood flow and oxygen levels to indicate neural activity. When a particular brain area is more active, it consumes more oxygen, and blood flow increases. WebThe procedure for a functional MRI is very similar to that of a regular MRI. The patient lies face-up on a flat surface and is rolled into a long tubular machine. ... The main difference between the two procedures is that during an fMRI, doctors give the patient instructions and ask him or her to complete silent brain exercises while lying still.
