Outline of Final Research Achievements

Contrast agents are used to enhance the contrast of the lesion. MRI contrast agents specific for the reticular system, such as the liver, are already widely used in clinical practice and have achieved significant results in terms of tissue selectivity. However, the MRI contrast agents currently used in clinical practice are less specific to specific diseases, such as cancer, and are still under development. In this study, we developed a new MRI contrast agent that incorporates molecular imaging technology to visualize specific molecules using cellular functions. Furthermore, by combining high-sensitivity and disease-response technologies, we have developed a nanocontrast agent with both sensitivity and functionality.

Academic Significance and Societal Importance of the Research Achievements

MRIの国内設置台数はすでに7000台を越え、臨床診断装置として不可欠な役割を担っている。ハードとソフト両面におけるMRI装置の進歩は、撮像の時間分解能や画像の空間分解能など画像診断情報の質を向上させ、MRIの対象領域をますます拡大している。しかしながらその撮影原理上、MRIによって病変部位を特異的に描出することは困難であり、ほとんどの場合、単純な形態診断法して使われている。この欠点を補完し、疾患特異的な機能性造影剤の開発に成功した。
