The question was about an electric field - not a magnetic field.

Oddly enough, related to the dielectric properties which you dismissed

No, MRI has nothing to do with detecting changes in a magnetic field
induced by tissue constituents. The magnetic field is used to hold the
tissue's atoms in a state where they can be imaged by detecting their
interactions with radio waves of specific frequencies.
I feel you should stop "explaining" things you don't understand - it
certainly doesn't help anyone.
