Molecular imaging is a multidisciplinary field that combines various imaging techniques with molecular biology to visualize, characterize, and quantify biological processes at the molecular and cellular levels within living organisms. This area of research encompasses a variety of imaging modalities, including: 1. **Positron Emission Tomography (PET)**: A nuclear medicine imaging technique that detects gamma rays emitted indirectly by a tracer, which is usually a biologically active molecule labeled with a radioactive isotope.
