WebHow SPECT Differs from MRI, fMRI, and PET. A SPECT scan is similar to an MRI study in that both can show 3D images of the brain. However, whereas MRI shows the physical anatomy or structure of the brain, … WebThe basis of fMRI is the different magnetic properties of oxygenated and deoxygenated blood. Due to a stimulus, increased flow of oxygenated blood into regions of brain activity causes the changes in the MR signal. This results in the corresponding changes in MRI map which are captured as four dimensional (x, y, z, t) fMRI images. Automated,
