Thallium-201 and Technetium-99m-Pyrophospate Myocardial Imaging in the Coronary Care Unit【電子書籍】
楽天Kobo電子書籍ストア
|
<p>Noninvasive visualization of myocardial infarction using radionuclides dates back over eighteen years. Edward A. Carr and William H. Beierwaltes were first to report (1962) successful external imaging of myocardial infarcts in dogs and in man using an Anger scintillation camera. They demonstrated that after intravenous administration of 86Rb or l3ICS an infarct was visualized as a "cold spot", while 203Hg-labeled-chlormeridin resulted in a "hot-spot" image of the infarct. Since then, there have been major developmental improvements in avail able radionuclides, scintillation cameras and computer processing capabilities. In particular, the development of mobile gamma cameras opened the possi bility to obtain high quality images even at the bedside of critically ill patients. Since the development in 1974 of a new radiopharmaceutical, 20lTI and the application of 99mTc-pyrophosphate for myocardial imaging, these imaging agents are widely used for the detection of acute myocardial infarction. However, for practical application, frequently there appears to be uncertainty or even confusion concerning the relative merits of each method.</p>画面が切り替わりますので、しばらくお待ち下さい。 ※ご購入は、楽天kobo商品ページからお願いします。※切り替わらない場合は、こちら をクリックして下さい。 ※このページからは注文できません。

The Poetry of Technetium【電子書籍】[ Walter the Educator ]
楽天Kobo電子書籍ストア
|
<p>"Earning a degree in chemistry changed my life!" - Walter the Educator. This book is dedicated to all the chemistry lovers, like myself, across the world. <em>The Poetry of Technetium</em> belongs to the Chemical Element Poetry Book Series by Walter the Educator?. Collect all books in the series at WaltertheEducator.com. Creating a poetry book about the chemical element of Technetium was a unique and fascinating endeavor. Technetium is an intriguing element in the periodic table as it is the first element to be artificially produced. It has various applications in nuclear medicine and research. By exploring the characteristics and properties of Technetium through poetry, I can delve into its scientific significance, historical context, and symbolic representations. This approach allows for a creative fusion of science and art, bringing together the worlds of chemistry and poetry. It can also serve as a means to educate and engage readers in a different way, making science more accessible and relatable.</p>画面が切り替わりますので、しばらくお待ち下さい。 ※ご購入は、楽天kobo商品ページからお願いします。※切り替わらない場合は、こちら をクリックして下さい。 ※このページからは注文できません。

Radionuclide and Radioisotope Encyclopedia: Cesium-137, Iodine-131, Plutonium, Cobalt, Tritium, Radium, Strontium, Technetium-99, Thorium, Uranium - Radiation Health Effects and Toxicology【電子書籍】[ Progressive Management ]
楽天Kobo電子書籍ストア

<p>This authoritative, 1800 page collection of official documents provides comprehensive details about the health and medical impacts of eleven important radioisotopes, some of which are major factors in nuclear power plant accidents: Cesium-137, Iodine-131, Plutonium, Cobalt, Tritium, Radium, Strontium, Technetium-99, Thorium, Uranium, and Americium. Many have a complete toxicological profile from the Agency for Toxic Substances and Disease Registry (ATSDR).</p> <p>CESIUM: Radioactive cesium-137 is produced when uranium and plutonium absorb neutrons and undergo fission. Examples of the uses of this process are nuclear reactors and nuclear weapons. The splitting of uranium and plutonium in fission creates numerous fission products. Cesium-137 is one of the more well-known fission products. Cesium-137 in the environment came from a variety of sources. The largest single source was fallout from atmospheric nuclear weapons tests in the 1950s and 1960s, which dispersed and deposited cesium-137 world-wide. However much of the cesium-137 from testing has now decayed. Nuclear reactor waste and accidental releases such as the Chernobyl accident in the Ukraine release some cesium-137 to the environment. Spent nuclear fuel reprocessing plant wastes may introduce small amounts to the environment.</p> <p>IODINE: A large amount of epidemiological literature exists on the health outcomes in populations that were exposed to environmental releases of radioiodine. These include releases from explosions of nuclear bombs such as the Marshall Islands BRAVO test, the largest U.S. detonation (15 megatons), and from the Nevada Test Site; releases from nuclear fuel production facilities such as the Hanford Nuclear Site; and accidental releases from nuclear power plants such as the Chernobyl explosion and fire. In general, releases of these types result in mixed exposures to a variety of radioisotopes and to radiation doses from both external and internal exposure. However, doses from radioiodine that are significant to health derive largely from internal exposure as a result of uptake of relatively short-lived radioiodine isotopes into the thyroid gland. Thus, effects on the thyroid attributable to radioiodine that were subsequently observed, in some cases, years after the event, derived from exposures to the relatively high levels of radioiodine found immediately after the event, rather than from sustained exposures.</p> <p>PLUTONIUM: Plutonium is a silvery white metal that exists as a solid under normal conditions. It is produced when uranium absorbs an atomic particle. Trace amounts of plutonium occur naturally, but large amounts have been produced in nuclear reactors. Trace levels of plutonium can be found in the environment, from past nuclear bomb tests, in several forms called isotopes. The most common plutonium isotopes are plutonium-238 and plutonium-239. Plutonium undergoes radioactive decay.</p> <p>This is a privately authored news service and educational publication of Progressive Management.</p>画面が切り替わりますので、しばらくお待ち下さい。 ※ご購入は、楽天kobo商品ページからお願いします。※切り替わらない場合は、こちら をクリックして下さい。 ※このページからは注文できません。
