used in medical imaging.. how did they ever find out which radiotracers would be good for what?
Radiotracers are radioactive substances that are used in medical imaging to track the movement and distribution of specific molecules in the body. They emit gamma rays that can be detected by imaging machines, providing detailed information about the location and function of the molecules.
Radiotracers are made by combining a radioactive isotope with a biologically active molecule. This can be done through a process called radiolabeling, where the radioactive isotope is chemically attached to the molecule. The specific molecule chosen will depend on the area of the body being studied.
Radiotracers allow for non-invasive imaging of the body, providing valuable information about the structure and function of organs and tissues. They can also help diagnose and monitor diseases, such as cancer, by visualizing changes in cellular activity and metabolism.
The amount of radiation exposure from radiotracers is very small and considered safe for medical use. However, as with any medical procedure, there is a small risk of allergic reactions or adverse effects. Your doctor will weigh the potential risks against the benefits of using radiotracers for your specific case.
The radioactive material in radiotracers decays over time and is eliminated from the body through natural processes, such as urine or feces. The length of time for this to occur varies depending on the specific radiotracer used, but it typically takes a few hours to a few days for the radioactivity to be completely cleared from the body.
