Is technetium 99m safe for patients?
Technetium-99m has a photopeak of gamma-ray emission of 140.5 keV, making it a very minimal risk of toxicity. [3] The short six-hour half-life and rapid excretion from the body limit toxic effects and give enough time to perform its diagnostic imaging, all while limiting radiation exposure to the patient.
What are the dangers of technetium?
It is a radioactive isotope of Technetium (Tc-99m). This product can cause: allergic reactions, anaphylaxis, tearing, radioactive material: may cause cancer, adverse reproductive effects, embryo/fetal toxicity, gout.
What are the disadvantages of technetium 99m?
It gives high yields of 99Mo of very high specific activity. However, its main disadvantages are high costs and generation of large quantities of highly radioactive waste. Depending on the separation method several types of generators were developed.
What are the side effects of a bone scan?
A bone scan generally has no side effects, and no follow-up care is needed. The radioactivity from the tracers is usually completely eliminated two days after the scan.
Is technetium poisonous or hazardous?
Technetium has no biological role. Technetium does not occur naturally in the biosphere and so normally never presents a risk. All technetium compounds should be regarded as highly toxic, largely because of its radiological toxicity.
What is technetium 99 used for in medicine?
Technetium-99m is used to image the skeleton and heart muscle in particular, but also for brain, thyroid, lungs, liver, spleen, kidney, gall bladder, bone marrow, salivary and lachrymal glands, heart blood pool, infection and numerous specialized medical studies.
What is technetium used for?
Technetium (Tc-99m) is an isotope commonly used in a number of medical diagnostic imaging scans. Tc99m is used as a radioactive tracer for nuclear medicine; which is a form of medical imaging that assesses how particular parts of our body are working or functioning.
Is bone scan harmful?
A bone scan doesn’t cause any side effects or complications. Most of the radioactive tracer is eliminated from your body within 24 hours. Small amounts may remain for as long as three days. While the test can help identify problems in bone metabolism, it doesn’t necessarily reveal the reason for them.
Does a bone scan show arthritis?
Bone scans are used to detect arthritis, neoplasm, fractures and sports injuries, tumors and metastatic disease, as well as to evaluate unexplained bone pain.
Why is technetium used in bone scans?
Technetium-99m methylene diphosphonate (MDP) is one of the most commonly used tracers for SS and its mechanism of action involves a complex interaction of bone repair and blood flow. SS targets the bony cortex, binding to the hydroxyapetite produced when the bone attempts to repair damage caused by metastases.
