The chemistry of radioactive materials is known as radiochemistry. The presence of trace amounts of radioactive reagents distinguishes radiochemistry from conventional chemistry. The quantities of radioactive molecules in the combination are frequently lower than the contaminants introduced by solvent and other reagents. One of the primary tools for biomedical science is the radio isotopically labelled parent drug or its metabolite, which operates like and can trace its non-radioactive counterpart. Scientists have been able to analyze practically every element of a drug's behavior in vivo thanks to these radiolabeled molecules.
Hybrid imaging technology offers the ability to provide "one-stop" imaging with improved specificity, attenuation correction, and localization, allowing for more precise diagnosis. The fusing of two or more imaging methods into a single, new form of imaging is known as hybrid imaging. This new form is usually synergistic, meaning it is more potent than the sum of its parts.
Small amounts of radioactive materials called radiotracers are injected into the bloodstream, inhaled, or ingested in nuclear medicine imaging. Nuclear medicine imaging gives information that conventional imaging procedures cannot always provide, and it has the potential to detect disease at an early stage.
