Ace the MRI Challenge 2026 – Dive Into the World of Magnetic Magic!

The term that describes the extent to which a tissue becomes magnetized in an external magnetic field is magnetic susceptibility. This property indicates how much a material will become magnetized when subjected to an external magnetic field, and it is measured as a dimensionless ratio. Different tissues have varying susceptibilities due to their molecular composition, which affects how they respond to magnetic fields during MRI examinations.

Magnetic resonance refers to the phenomenon that occurs when nuclei in a magnetic field absorb and re-emit electromagnetic radiation, while magnetic flux is related to the quantity of magnetic field lines passing through a surface area. Magnetic fields themselves are the regions around magnetic materials where magnetic forces can be observed. Each of these concepts plays a role in MRI technology, but magnetic susceptibility specifically quantifies the magnetization of tissues in response to an external field.
