Figure 2: The study of the radiopharmaceutical excitation mechanism.
From: In vivo nanoparticle-mediated radiopharmaceutical-excited fluorescence molecular imaging
(a,b) EO is excited by 18F-FDG (a) and 99mTc-MDP (b) with different radiation blocking conditions. From row I to V: normal view, black box blocking CL, aluminium foil blocking β+, lead torus blocking γ, normal view. (c,d) The emission intensity of each condition is plotted for using 18F-FDG (c) and 99mTc-MDP (d), respectively. Both cases reveal obvious intensity decrease in Condition IV. The slight intensity decrease from Condition I to V in (c) indicates the relatively shorter half life of 18F.
