What is molecular imaging?
img01 The molecular imaging that we engage in is a technology for examining the in vivo dynamics of a variety of biologically active molecules, such as genes and proteins, present in a living organism. Among the techniques of molecular imaging is Positron Emission Tomography (PET) which uses a positron-emitting radionuclide to quantify and visualize their functionality in the body. Because PET is more sensitive and more accurate than other molecular imaging techniques, positron-labeled compounds permit highly accurate quantitative analysis of even minute amounts of the imaged molecule. Another advantage is their ability to enable the three-dimensional visualization of pathophysiological and pathobiochemical changes with minimum burden on the body because of low radiation exposure due to their short half-life.
