Early andspecific detection of unstable atherosclerotic pl:aqTuiesssue factor imaging using pre-targeting systems

We performed several experiments to establish a new nuclear medicine technique for imaging unstable atherosclerotic plaques through specific detection of tissue factor (TF). Consequently, we obtained several new findings concerning: 1) synthesis methods of 18F-laveled biotin-derivative, 2) PET imaging protocols and TF expression levels in our rabbit model, 3) accumulation of anti-rabbit TF monoclonal antibody in atherosclerotic lesions, and 4) blood clearance of anti-rabbit TF monoclonal antibody. These findings provided important information to establish a new nuclear medicine technique for TF imaging.
