radioactive isotopes in medicine

Nitrogen Used in PET scans as a blood flow tracer and in cardiac studies. Both bone and soft tissue can be imaged successfully with this system. Other types of imaging Positron Emission Tomography PET scans A widely-used nuclear imaging technique for detecting cancers and examining metabolic activity in humans and animals.

How are radioactive isotopes produced? Used in a variety of research and diagnostic applications, including the labeling of glucose as fluorodeoxyglucose to detect brain tumours via increased glucose metabolism.

Medical applications use artificial radioisotopes that have been produced from stable isotopes bombarded with neutrons. Nuclear imaging Nuclear imaging is a diagnostic technique that uses radioisotopes that emit gamma rays from within the body.

Thallium Used in imaging to detect the location of damaged heart muscle.

Radioisotopes wikipedia

Organic materials typically contain small amounts of radioactive carbon and potassium. There are several sources of radioactive isotopes. How is nuclear imaging different to other imaging systems? How does nuclear imaging work? Glucose carries the positron emitter to areas of high metabolic activity, such as a growing cancer. Carbon Top Questions What is a radioactive isotope? Other types of imaging Positron Emission Tomography PET scans A widely-used nuclear imaging technique for detecting cancers and examining metabolic activity in humans and animals. A small amount of short-lived, positron-emitting radioactive isotope is injected into the body on a carrier molecule such as glucose. One way of artificially inducing nuclear transmutation is by bombarding stable isotopes with alpha particles. The radioisotope circulates through the body or is taken up only by certain tissues. Only hydrogen-3 tritium , however, is a radioactive isotope; the other two are stable. Learn more about radiation. Cosmic radiation from the Sun and other stars is a source of background radiation on Earth.

In radiotherapy, radioisotopes typically are employed to destroy diseased cells. The information is then processed to show a 3-D cross-section of body tissues and organs. Iodine Used in imaging to monitor thyroid function and detect adrenal dysfunction.

Benefits of radioisotopes

Gallium Used in imaging to detect tumours and infections. Thallium Used in imaging to detect the location of damaged heart muscle. More than 1, radioactive isotopes of the various elements are known. The radioisotope circulates through the body or is taken up only by certain tissues. Other types of imaging Positron Emission Tomography PET scans A widely-used nuclear imaging technique for detecting cancers and examining metabolic activity in humans and animals. Carbon Both bone and soft tissue can be imaged successfully with this system. The primary advantage of PET imaging is that it can provide the examining physician with quantified data about the radiopharmaceutical distribution in the absorbing tissue or organ. The information is then processed to show a 3-D cross-section of body tissues and organs. Used in a variety of research and diagnostic applications, including the labeling of glucose as fluorodeoxyglucose to detect brain tumours via increased glucose metabolism. How does nuclear imaging work? Radioactive isotopes have many useful applications. Fluorine 1. A radiopharmaceutical is given orally, injected or inhaled, and is detected by a gamma camera which is used to create a computer-enhanced image that can be viewed by the physician. Glucose carries the positron emitter to areas of high metabolic activity, such as a growing cancer.

Carbon Radioactive isotopes of radiumthoriumand uraniumfor example, are found naturally in rocks and soil. See Article History Alternative Titles: radioactive nuclide, radioisotope, radionuclide Radioactive isotope, also called radioisotope, radionuclide, or radioactive nuclide, any of several species of the same chemical element with different masses whose nuclei are unstable and dissipate excess energy by spontaneously emitting radiation in the form of alphabetaand gamma rays.
