(Functional Magnetic Resonance Imaging) An imaging of the brain using MRI technology, fMRI scan uses radio waves and a strong magnetic field to measure the levels of blood in specific parts of the brain.
Functional Magnetic Resonance Imaging. A type of imaging that measures increases in blood flow within the brain.
a form of magnetic resonance imaging of the brain that registers blood flow to functioning areas of the brain
a non-invasive method that measures blood flow, while PET and SPECT methods involve the injection of radioactive materials
functional Magnetic Resonance Imaging. Functional MRI is based on the increase in blood flow to the local vasculature that accompanies neural activity in the brain. Using an appropriate imaging sequence, human cortical functions can be observed without the use of contrast enhancing agents on a clinical strength scanner. Functional activity of the brain determined from the magnetic resonance signal has confirmed known anatomically distinct processing areas in the visual cortex, the motor cortex, and Broca's area of speech and language-related activities.

abbreviation for Functional Magnetic Resonance Imaging (fMRI), a technique using very rapidly acquired magnetic resonance images (MRIs) in order to capture blood flow changes during a cognitive, sensory or motor task
Functional Magnetic Resonance Imaging is the process of using MRI scanners to obtain information about the activity occurring inside the brain by measuring the metabolic consumption of oxygen as expressed by small variations in magnetic flux.
Functional Magnetic Resonance Imaging, a new method of scanning the brain's activity that needs no radioactive materials and produces images at a higher resolution than PET. It is based on differences in the magnetic resonance of certain atomic nuclei in areas of neuronal activity.
Stands for "functional magnetic resonance imaging." This technique uses magnetic fields to measure oxygen use by nerve cells in the brain. It allows researchers to determine which specific areas of the brain are most active during a task.
