How come the iron in our blood doesn’t seep out during an MRI scan?
In: Chemistry
The iron in your blood exists as individual ions which are then bound to proteins. These ions are restricted in movement and cannot easily form magnetic domains, where each iron atom in a domain is “pointing” in the same direction. This is a pre-requisite for magnetic properties.
Since the iron in your blood cannot from magnetic domains, it cannot demonstrate significant magnetic properties and will not be attracted out of your body by the MRI.
