Outline of Final Research Achievements

The results obtained by our research are as follows.
(1) An automated synthesis method for 18F-RGD-K5 (an integrin αvβ3 imaging agent) has been successfully established. (2) Unlike 18F-FDG, 18F-FMISO (an hypoxia imaging agent) was found to accumulate in M2 macrophages present in hypoxic environment. (3) It was also confirmed that 2-nitroimidazole compounds selectively accumulated in the atherosclerotic regions of a rabbit model.
These results would contribute to establish diagnostic imaging of atherosclerosis.
