Nuclear medicine is a branch of medical science, which uses small amounts of radioactive materials in order to diagnose and treat diseases. These diseases include cancers, heart diseases, and other irregularities in the body. The nuclear medicine is injected into the blood stream in order to identify potential diseases. There are over forty million nuclear medicine procedures preformed each year through radiation, or the energy in form of waves or high speed particles. The use of nuclear medicine allows the treatment of diseases without surgery. This form of treatment causes only minimal damage to the tissues surrounding cancerous cells. Radiotracers help doctors diagnose and evaluate the degree of severity of the disease. The tracers are injected, swallowed, or inhaled. Special cameras used by the doctor to detect molecular information then detect the emissions from the radiotracers. One of the most important procedures in nuclear medicine is the MRI, or the magnetic resonance …show more content…
Radiation can also be used to treat organs and tumors. There are over ten thousand hospitals that use radioisotopes in medicine. The most common isotope is technetium—99. Technetium—99 is used around 20 million times each year. The amount of radiation this isotope gives off is low, and therefore not harmful to the patient. The amount of radiation an injection of technetium—99 is 250 MBq. This number is far below boundary of radioactivity harm. Important attributes of medical nuclear isotopes are their small half-lives. A half-life is the time it takes for half of a sample of an isotope to decay. Technetium—99, for example, has a six-hour half-life. Although short, this half-life allows enough time for testing. After this time period, the isotope will lose some of its radiation. The minute half-life allows very little time for any damage
Nuclear energy is used today for energy supply and about 15% of the world’s energy comes from nuclear power plants some forms of medicine such as nuclear medicine rely
Nuclear medicine is a certain branch of medicine that uses a specific type of radiation to give out important information about how a person's specific organs work. As well as, showing the organ and treating a disease that is inside of it. When information gets viewed by special physicians, they make sure to get a quick, accurate diagnosis of what the patient's illness is right away. The main organs that can be easily imaged by the nuclear medicine is the thyroid, bones, heart, liver, lungs, and the gallbladder. There are many hospitals that use the radiation; called radioisotope, in medicines. The most common one is named Technetium-99, which is used in medical diagnostic procedures annually. Nuclear medicine was created in the 1950s by physicians
The medical field also benefits from nuclear energy. Nuclear medicine is a field of medicine in which radioactive materials are used to diagnose and treat medical disorders
“Nuclear medicine is a highly specialized field of radiology. It requires the oral or intravenous administration of radiopharmaceuticals, radioactive isotopes combined with organ specific medications, in order to perform
The problems with using radioactive isotopes are if they get cancerous and you are human or animal it could stop them having children depending where you have the cancer in your body Also if that does happen it’s is going to stop the human/animal cycle because you can’t have kids. If you have cancer and they can’t cure it you are going to die and that going to be upsetting for your
Nuclear medicine technology has advantages and disadvantages just as any other career. Using nuclear medicine technology could diagnose a lot of harmful diseases. Also, it is more effective treatment for most categories of cancerous diseases and conditions in some medical institutions. This type of medicine technology helps physicians perform their responsibility of patients’ therapy easily; moreover, when a serious disease developed in the patient’s body, the x-rays of this medicine technology could scan the most sensitive part of the patient’s body.
Medicine has developed into an astonishing work of pure art over the years. From an old village healer crushing the simplest herbs in ancient times, to large machines administering chemical formulas to patients today. The newest addition to this artwork is Nuclear Medicine. Nuclear Medicine is a medicine that deals with the use of radioactive substances entering the body to attach/ attack cells. Whether it be to diagnose, test, or to treat, this nuclear technology has driven the medical and chemistry world into the future.
In nuclear medicine diagnosing techniques, a very small amount of radioactive material is introduced into the body. Because medical isotopes are attracted to specific organs, bones or tissues, the emissions they produce can provide crucial information about a particular type of cancer or disease. Information gathered during a nuclear medicine technique is more comprehensive than other imaging procedures because it describes organ function, not just structure. The result is that many diseases and cancers can be diagnosed much earlier.
Doctors had been using radiation to destroy cancerous cells since the unfolding of X-rays and radium in the 1890s, but both techniques had their own issues. X-ray machines were complicated to make use of, and radium implanted near tumors. In addition, X-rays weren’t strong enough to be entirely effective, and as for both of them, they were quite expensive.
Seaborg began working with one of the pioneers of nuclear medicine, Joe Hamilton, while attending Berkley. Hamilton needed a radioisotope that had a half-life long enough to be useful in dealing with in the human body; a half-life that was about a week. Seaborg and his long-time friend and partner, Jack Livingwood, used targets of tellurium and bombarded it with deuterons and some with neutrons to reveal iodine-131, which had a half-life of eight days. This element held major sentimental value to Seaborg due to its aid in his mother’s cure of hyperthyroidism. Iodine-131 is a major component still today in cancer treatment, particularly thyroid cancer. Seaborg and Livingwood also discovered cobalt-60, which is also a critical medical isotope. Cobalt-60 emits gamma radiation which in turn focuses directly on cancer cells to destroy it. “Hundreds of thousands of Americans have had their cancers treated by cobalt-60 irradiation, and it is also used to sterilize medical products and equipment” (36). Shortly
There are two other isotopes of technetium. One being technetium 98 and the other 99. Both of these have dramatically longer half-lives than there partner technetium 99m.
The nuclear medicine technologist use radionuclides to diagnose and treat diseases. Radionuclides means unstable atoms that release radiation spontaneously and they are purified and compounded to form radiopharmaceuticals that prepare and administer by nuclear medicine technologist. These technologists are particularly specialized health care professional. The radioactive drugs appear higher or lower concentration in the abnormal area of the patient’s body than in the normal area.
Issue: In medicine, radioisotopes are bonded with chemical compounds to form radioactive tracers, which are then injected into the patient’s bloodstream. The radiation emitted by the tracers allows doctors to obtain images of organ systems, facilitating the early and accurate diagnosis of disease. However, to avoid radio- active contamination, care must be taken in the storage, use, and disposal of this material.
Radiation therapy is the use of high-energy radiation from x-rays, gamma rays, neutrons, protons, and other sources to kill cancer cells and shrink tumors (National Cancer Institute, 2016). One of the main purposes of radiation is to preserve the normal cells while killing the cancer cells. To fully understand the importance of radiation therapy it is imperative to understand its discovery. The discovery of radioactivity is attributed to Henri Becquerel in Paris. His discovery was purely accidental, as most discoveries are, while attempting an experiment that utilized the sun, uranium, and photographic plates. On 26-27 February 1896, Henri Becquerel took the uranium and photographic plates wrapped in black paper to initiate his experiment by placing them in the path of sun light, but to his misfortune it was overcast both days. Thinking that his experiment was a failure, Becquerel decided to develop the photographic plates and found that uranium did not need the sun’s rays to emit radiation due to its own radioactive properties, thus discovering radioactivity. The actual term “radioactivity” was coined by Marie Curie, a Polish born physicist, who along with her husband had been studying the phenomenon that was discovered by Becquerel (Lawrence Berkely National Lab, 2000).
The use of radioactive elements in medicine is still growing to this day. Many oncologists use it to treat their patients who have cancer. Many cancer patients use this option. They use the radiation to kill off cancer cells. X-ray technicians or radiologists will also use it to administer x-rays to people who may have a broken bone, or need an MRI. The patient is injected with a radioactive material that helps the doctor be able to see inside the body better, whether it be with pictures or ultrasound. Radioactive material is defined as “material that contains radioactivity and thus emits ionizing radiation. It may be material that contains natural radioactivity from the environment or a material that may have been made radioactive.” (The Healthy Physics Society). This happens when someone needs a colonoscopy. They have to drink or are injected with this liquid that helps their organs and all other masses in the body be seen better by the radioactive materials.
