Radiotraceren

Radiotraceren, also known as radiotracer, is a radioactive substance used in medical imaging and diagnostic procedures to track the movement of substances within the body. It is typically a small molecule or compound that is labeled with a radioactive isotope, such as technetium-99m, iodine-123, or fluorine-18. These isotopes emit gamma rays or positrons that can be detected by specialized imaging equipment, allowing for the visualization of specific organs, tissues, or metabolic processes.

Radiotraceren is commonly used in nuclear medicine to diagnose and monitor various conditions. For example, technetium-99m-labeled red blood cells can be used to assess blood flow and detect blockages in the heart or brain. Iodine-123-labeled thyroid hormones can help diagnose thyroid disorders, while fluorine-18-labeled glucose can be used to study brain metabolism. Radiotraceren is also used in oncology to detect and monitor the spread of cancer cells.

The use of radiotraceren in medical imaging has revolutionized the diagnosis and treatment of various diseases. However, it also carries risks, including exposure to ionizing radiation, which can cause tissue damage and increase the risk of cancer. Therefore, the use of radiotraceren is carefully regulated and monitored to ensure patient safety.
