Sorry if this is the wrong area, but this is the best one I could find. What is the basic difference between MRI and fMRI imaging techniques? MRI is less invasive MRI carries less risk to the patient fMRI provides less detail fMRI allows for real-time observations of changes in brain activity neither shows soft tissue structures of the brain

    i would say that fmri is a type of mri both are magnetic resonance imaging but fmri is used to determine the particular part of the brain involved in a certain process hence the reason for the name 'functional magnetic resonance imaging' it does not involve radiation so it is quite comfortable for patients...

    FMRI scans use the same basic principles as MRI scans, but MRI scans image anatomical structure (not functions) whereas FMRI image metabolic function. So, the images generated by MRI scans are like three dimensional pictures of anatomic structure. The images generated by FMRI scans are images of metabolic activity within these anatomic structures.

    This is a totally valid Health Science question. You're in the right area. And MRI lets you look at the structure of the brain. We can use an MRI to look at the brain, and tell whether it looks normal, or something looks a bit odd, about it. The fMRI does something that the MRI cannot: The fMRI can track blood flow throughout the brain, and show us which areas of the brain are more active, at the moment. So, the fMRI is more about "real time observations." It can tell us what's happening with the brain, right now. It can tell us which parts of the brain are using more oxygen, because they are more active.
