Super-paramagnetic iron oxide nanoparticles (SPIONs) have been widely explored as novel magnetic resonance imaging (MRI) contrast agents because of a combination of favorable super-paramagnetic properties, biodegradability, and surface properties. Among the numerous MNPs under examination, SPIONs have involved considerable interest due to their outstanding magnetic properties, biocompatibility, and biodegradability. This review debates the ABCs of MR imaging, reports and informs the state of the art of magnetic nanoparticles in cancer dealing the source of SPIONs' exclusive magnetic properties, recent progresses in MRI acquisition methods for detection of SPIONs.
