magnetic susceptibility

a measure of the ability of a substance to become magnetized.

magnetic susceptibility

An MRI term for the extent to which a tissue becomes magnetised when placed within a magnetic field. Magnetic susceptibility disparity at tissue boundaries are a well-known cause of MRI artefact.
