      What does a Nuclear Medicine Specialist do?

      Nuclear Medicine Specialist has expertise in using the properties of radioactive atoms and molecules for the diagnosis and treatment of various diseases, as well as for medical research purposes. Diseases are detected by using radiation detection and imaging instrument systems, as this technique changes the functionality and metabolism of normal body cells, tissues and organs. This approach can reveal a wide range of diseases, often before structural abnormalities in the affected organ are detectable using other techniques. Key applications include the early detection of coronary artery disease (including acute heart attacks), early cancer diagnosis and treatment evaluation, as well as diagnosing infections and inflammation throughout the body. Additionally, these techniques can facilitate the early detection of blood clots in the lungs. Unique forms of radioactive molecules are used to attack and destroy cancer cells (such as those found in lymphoma and thyroid cancer) or alleviate severe pain associated with cancer that has metastasized to the bones.
