MRI is based upon the science of nuclear magnetic resonance (NMR). Certain atomic nuclei can absorb and emit radio frequency energy when placed in an external magnetic field. In clinical and research MRI, hydrogen atoms are most-often used to generate a detectable radio-frequency signal that is received by antennas in close proximity to the anatomy being examined. Hydrogen atoms exist naturally in people and other biological organisms in abundance, particularly in water and fat. For this reason, most MRI scans essentially map the location of water and fat in the body. Pulses of radio waves excite the nuclear spin energy transition, and magnetic field gradients localize the signal in space. By varying the parameters of the pulse sequence, different contrasts can be generated between tissues based on the relaxation properties of the hydrogen atoms therein.

My feeling is that the social brain has many levels. If you don’t understand the foundational level, then you can do brain imaging until you’re blue in the face, but you still will not understand the process at a deep causal level.
If you understand the fact that quantized energy must be linked from the anti-entropic virucidal energy of sunlight to diagnostic testing by what is known to serious scientists about the effects of energy on hydrogen-atom transfer in DNA base pairs in solution, you may understand how frustrating it is to see people report pseudoscientific nonsense like this:

I urge others who are interested in learning more about energy-dependent endogenous RNA interference and biophysically constrained viral latency to search for the term microRNA and the form of pathology that links the failure of RNA-mediated protein folding chemistry to the disease. You can be as specific or as general as you wish and you will still find that the energy-dependent creation of G protein-coupled receptors, enzymes, hormones et al., must be linked from ecological variation to ecological adaptation by the physiology of reproduction. That fact refutes the pseudoscientific basis for the CRISPR threat to humanity.
See for comparison the never ending nonsense touted by theorists who know nothing about mRNA stability:
We suggest that dogs spontaneously recognized the chasing-like pattern and thus they may have considered the interacting partners as animate agents. This methodological approach may be useful to test perceptual animacy in other non-human species.
