Web28 mei 2024 · How does an fMRI work? Copyright: FMRIB Centre Functional magnetic resonance imaging, or FMRI, works by detecting the changes in blood oxygenation and flow that occur in response to neural activity– when a brain area is more active it consumes more oxygen and to meet this increased demand blood flow increases to the active area. Web13 apr. 2024 · fMRI baseia-se na mesma tecnologia que imagem de ressonância magnética ( Ressonância magnética) - um teste não invasivo que utiliza um campo magnético forte e ondas de rádio para criar imagens detalhadas do corpo.
