Microspheres have been the most commonly used embolic agents in clinical embolotherapy. However, most of the embolic microspheres used currently cannot be visualized under routine clinical imaging equipments, such as computed tomography (CT) or magnetic resonance imaging (MRI). Thus, the position and distribution of the microspheres cannot be monitored timely and accurately. In order to improve the efficacy and safety of embolization, a variety of MRI-visible embolic microspheres have been developed in recent years, but no related review has been found. Here, we summarized the MRI “visualized” embolized microspheres reported in literatures for their design, preparation and evaluation so as to provide a useful reference for the further research and development of such microspheres.
