Non-invasive imaging of endogenous magnetic particle deposits in biological tissue using magnetic resonance imaging

Homing pigeons are able to navigate using the Earths magnetic field. This magnetic sensing ability is linked to the presence of trace quantities of naturally occurring iron-based magnetic particles in the tissue of the bird. This study investigated the use of MRI to obtain high resolution in vitro images of a pigeon head and located regions of discrete hypointensity areas along the upper beak tissue that may correspond to these iron-based magnetic particle deposits.
