Cell tracking via MRI has drawn much attention recently for its sensitive, deep, and real-time properties and high spatial resolution. In a previous chapter, the labeling and tracking of superparamagnetic iron oxide (SPIO)-nanoparticle-loaded stem cells have been well summarized (Sykova et al., Methods Mol Biol 750:79–90, 2011). Thus, in this chapter, we will mainly focus on the tracking of SPIO-nanoparticle-labeled mouse dendritic cells by MRI and provide a detailed protocol for cell labeling and in vivo tracking by a clinical 3.0T MRI scanner. Of note, this protocol is also suitable to be applied on other types of cells.
