Why do u think its important that radioactive isotopes used internally for diagnosis or treatment have relatively short half-lives?
Some radioisotopes used in nuclear medicine have short half-lives, which means they decay quickly and are suitable for diagnostic purposes; others with longer half-lives take more time to decay, which makes them suitable for therapeutic purposes.
Why is the radioactive isotope important?
Radioactive isotopes have many useful applications. In particular, they are central to the fields of nuclear medicine and radiotherapy. In nuclear medicine, tracer radioisotopes may be taken orally or be injected or inhaled into the body.
Why are radioactive isotopes used in medicine?
Therapeutic applications of radioisotopes typically are intended to destroy the targeted cells. This approach forms the basis of radiotherapy, which is commonly used to treat cancer and other conditions involving abnormal tissue growth, such as hyperthyroidism.
Which radioactive isotopes can be beneficial in diagnosing and treating diseases?
The most common radioisotopes used in the medical industry are Technetium-99m, Iodine-131, and Molybdenum-99. 85% of all nuclear medical examinations use Mo/Tc generators for diagnosing problems with the liver, bones, or lungs [6].
Why is it important that radioisotopes used in diagnostic tests?
Radioisotopes are an essential part of medical diagnostic procedures. In combination with imaging devices which register the gamma rays emitted from within, they can be used for imaging to study the dynamic processes taking place in various parts of the body.
What is the role of radioactivity in the diagnosis of disease?
Since Rontgen's discovery over 100 years ago, radiation has been used to create visual images of the inside of the body to diagnose medical conditions. Medical professionals use ionizing radiation in specific imaging procedures to help diagnose injuries or illness within the body.
Why is it safe to use radioisotopes for the diagnosis of medical problems?
When used in carefully controlled medical applications, radioactive isotopes are safe and not nearly as scary as we first imagined. The radiation from these isotopes have a short half life and only give off low levels of radiation.
How are radioactive elements used for medical diagnosis quizlet?
How are radioactive elements used for medical diagnosis? The elements are placed in special cameras which record images from emitted radiation, like x-ray equipment. The radiation from certain elements can penetrate the entire body and expose all internal organs to photographic film.
Why is it important that radioisotopes used in diagnostic tests have short half lives quizlet?
Why is it important that radioisotopes used in diagnostic tests have short half-lives? This minimizes the harmful side effects of the radiation.
Why is nuclear medicine is the best option in the treatment of some diseases nowadays?
Benefits and Risks of Nuclear Medicine Provides information on how organs, tissues, and cells are working. (Other common imaging procedures only show the structures.) Can be used also in targeted treatments to kill or damage harmful or cancerous cells, reduce the size of tumors, or reduce pain.
Where are radioactive isotopes used?
The most widely used radioactive pharmaceutical for diagnostic studies in nuclear medicine. Different chemical forms are used for brain, bone, liver, spleen and kidney imaging and also for blood flow studies. Used to locate leaks in industrial pipe lines…and in oil well studies.
