Functional MRI can detect the difference in signal caused by the increase in blood flow to specific areas of the brain. #FunctionalMRI #fMRI #brainMapping #DTI #diffusiontensorimaging
Functional MRI (magnetic resonance imaging) is a noninvasive diagnostic test that measures small changes in blood flow as a person performs tasks while in the MRI scanner. Functional MRI detects the brain in action (e.g., speaking or moving). It has an advantage over other imaging studies that focus only on the structure of the brain. This test helps doctors understand how a tumor or a stroke has altered brain function. It is also an important to...
