Radioligands are molecules that have been labeled with a radionuclide, meaning they emit radiation. This property makes them invaluable tools in various scientific fields, particularly in medical imaging and biological research. The radionuclide incorporated into the radioligand allows for its detection and quantification using specialized equipment.

In nuclear medicine, radioligands are used as radiopharmaceuticals for diagnostic imaging techniques such as Positron Emission Tomography (PET) and Single-Photon Emission Computed Tomography (SPECT). These imaging modalities rely on the emitted radiation from the radioligand to visualize physiological processes and the distribution of specific targets within the body. For example, a radioligand might be designed to bind to a particular receptor or enzyme involved in a disease, allowing clinicians to assess its presence and activity.

Beyond medical imaging, radioligands are crucial in pharmacological research to study drug-receptor interactions, drug metabolism, and biodistribution. By tracking the fate of a radioligand, researchers can gain insights into how potential therapeutic agents behave in biological systems. The choice of radionuclide and the design of the ligand itself are critical factors in determining the suitability of a radioligand for a specific application, influencing its half-life, energy emission, and binding affinity.
