Numbers are not exact, and may change slightly in the future, as "stable nuclides" are observed to be radioactive with very long half-lives. This is a summary table [ 18 ] for the 989 nuclides with half-lives longer than one hour (including those that are stable), given in list of nuclides .
Radionuclide therapy (RNT, also known as unsealed source radiotherapy or molecular radiotherapy) uses radioactive substances called radiopharmaceuticals to treat ...
Radionuclide cisternography may be used to diagnose a spinal cerebrospinal fluid leak. CSF pressure is measured and imaged over 24 hours. [2] A radionuclide (radioisotope) is injected by lumbar puncture (spinal tap) into the cerebral spinal fluid to determine if there is abnormal CSF flow within the brain and spinal canal which can be altered by hydrocephalus, Arnold–Chiari malformation ...
Mayo Clinic Arizona is a multi-campus medical clinic and tertiary medical center in Phoenix, Arizona. Its two main campuses are the outpatient clinic building, situated in east Scottsdale, Arizona, and the Arizona Hospital, located in north Phoenix, Arizona. [ 1 ]
DOTA-TATE can be reacted with the radionuclides gallium-68 (T 1/2 = 68 min), lutetium-177 (T 1/2 = 6.65 d) and copper-64 (T 1/2 = 12.7 h) to form radiopharmaceuticals for positron emission tomography (PET) imaging or radionuclide therapy. 177 Lu DOTA-TATE therapy is a form of peptide receptor radionuclide therapy (PRRT) which targets ...
Radioactive contamination can be due to a variety of causes. It may occur due to the release of radioactive gases, liquids or particles. For example, if a radionuclide used in nuclear medicine is spilled (accidentally or, as in the case of the Goiânia accident, through ignorance), the material could be spread by people as they walk around.
Diagnostic tests in nuclear medicine exploit the way that the body handles substances differently when there is disease or pathology present. The radionuclide introduced into the body is often chemically bound to a complex that acts characteristically within the body; this is commonly known as a tracer. In the presence of disease, a tracer will ...
