Description
Summary:The rising demand for clinical diagnosis tools has led to extensive research on multimodal bioimaging systems. Unlike single‐modal detection, multimodal imaging not only can provide both function and structure information but also can address the issue of sensitivity, depth, and cost. Despite enormous efforts, conventional step‐by‐step procedures for obtaining multimodal imaging pose a significant constraint on their practical applications. In this work, X‐rays as highly penetrating radiation is proposed as a single‐irradiation resource, while lanthanide‐based nanostructure scintillators are employed as the single contrast agent to attenuate and convert X‐rays, achieving computer tomography (CT) and optical dual‐modal imaging at the same time. In other words, CT and optical dual‐modal imaging are simultaneously produced via single radiation combined with single contrast agent. The function and structure information of targeted tumors in a mouse model can be clearly provided with large penetration and high sensitivity, indicating that this strategy is a simple but promising route for multimodal imaging of molecular disease and preclinical applications. The single‐irradiation and dual‐modal imaging system, employing high‐penetrating X‐ray as the only excitation resource and Ln‐based nanostructure scintillators as single contrast agent, produces computer tomography and optical dual‐modal imaging at the same time and clearly provides the functional and structural information.
