Nanoparticles (NPs) are useful for radiotherapy. Currently, efforts are underway globally for the development of novel titanium dioxide NPs (TiO2-NPs) that exhibit both contrast effects and anti-tumor effects. In this study, the image contrast properties of TiO2-NPs were evaluated using a clinical magnetic resonance imaging (MRI) system and a clinical computed tomography (CT) scanner, as the use of TiO2-NPs as an anti-cancer agent has been reported in several reports. An obvious difference in visualization was observed between the control and TiO2-NP samples onT(2)-weighted images. These results suggest that TiO(2)can potentially be used as a novel theranostic drug with radiosensitizing ability and radiological diagnostic ability, through modification of chemical groups on its surface, and as a component of drug delivery systems.
