Molecular imaging is a technique that allows for the visualization, characterization, and measurement of biological processes at the molecular and cellular levels in humans and other living systems. It involves the use of various imaging modalities, such as positron emission tomography (PET), single-photon emission computed tomography (SPECT), magnetic resonance imaging (MRI), and optical imaging. By enabling the real-time observation of biological processes, molecular imaging provides insights into disease mechanisms and the effects of chemical agents on biological systems.
