Nuclear medicine is traced back to all sorts of sciences like physics, engineering, and chemistry. It is said that John Lawrence is the father of nuclear imaging because he was the first person ever to treat a leukemia patient with a radioisotope. From then on, a number of doctors experimented with patients with blood disorders and cancer by use of radioisotopes and were successful as well. One doctor’s procedure to halt the growth of cancer on the thyroid became the turning point in medical history. The beginnings of organ screening, for example PET scans, were born.

I’m inferring that most people only acknowledge the incidents related to radiation and such and nothing about how it benefits us, besides that it provides us with electricity. People don’t know that radioactivity is being put in patients to potentially save their lives. People don’t know how much nuclear chemistry has changed the face of science and society. People don’t know enough. I chose nuclear medicine as my topic to show mankind that nuclear chemistry isn’t all that bad. I wrote an editorial article because I know I could easily portray my perspective on it all and explain how it’s been working in the medical industry
The photons are then tracked by a tomographic scintillation counter, and the information is processed by a computer to provide both image and data on blood flow and metabolic processes within bodily tissues. PET scans are particularly useful for diagnosing brain tumor and the effects of strokes on the brain, along with various mental illnesses. They are also used in brain research and in mapping of brain functions.
People also benefit from atomic research in the medical field. Many people are aware of the wide use of radiation and radioisotopes in medicine. Nuclear medicine mostly uses radioisotopes which emit gamma rays from within the body. Estimates show that about one out of every three hospital patients benefits in some way from the use of nuclear medicine. Just think, every time you have an X-ray taken you are benefiting from nuclear research. Without X-rays, doctors would have a far greater time trying to set a broken bone if they even knew it was broken! Another common medical procedure that involves atomic research is the Cat-Scan. During this procedure the patient is injected with a radioactive isotope which shows the flow of blood through the
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.
1895 – X-rays were discovered accidentally by physicist Wilhelm Conrad Rontgen. Rontgen was working on a experiment and testing whether cathode rays could pass through glass. He noticed that a nearby tube emitted fluorescent glow of crystals. The air in the tube was released, high voltage applied, the same tube emitted a fluorescent glow. When Rontgen covered the tube in a heavy black paper, a green light could be seen. He concluded that a new light ray was being broadcast. Rontgen discovered that the light was very powerful and the same ray could pass through human tissue, but not through bones and metal objects. Medical applications were soon to follow.

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.
Nuclear Medicine is the use of radioisotopes for diagnosis, treatment, and research. Radioactive chemical tracers emit gamma rays which provides diagnostic information about a person's anatomy and the functioning of specific organs. Radioisotopes are also utilizes in treatments of diseases such as cancer. It is estimated that approximately one in two people in Western countries are likely to experience the benefits of nuclear medicine in their lifetime.
When it comes to medical imaging, there are several different options to choose from for different testing. There are similarities and differences; pros and cons to each. This paper will discuss MRI, CT, and ultrasound. They each have important things to know regarding radiation dose, cost, and reasons to use one over another.
Therapeutic nuclear medicine has come a long way over the last decade. More than 20 million Americans now benefit each year from nuclear medicine procedures used to diagnose and treat a wide variety of diseases (SNMMI and Safe/Beneficial Medical Uses of Radiation, 2017).
The first question I asked Dr. Kevin was, “Is nuclear pharmacy harmful to health?” He smiled and said that basically every student will ask this question because nuclear pharmacy sounds radioactive. By showing his dosimeter on his name tag and finger, we know the amount of radiation exposure will be strictly controlled. The female student who is currently training here told us that she delivered a healthy baby last year. Different organizations will inspect the amount of radioactive particles either on lab equipment or the pig container deliver to the health organization annually. The nuclear pharmacy has spectacular applications on diagnosis for multiple disease, such as indium 111 for white blood cell scan. The half life for radioactive
Physicians must ask themselves, “Is this CT the best examination to diagnose this condition in the child?” (National Cancer Institute, 2012). CT scans are quick, prevent misdiagnoses and unnecessary surgeries; however, there are two alternatives: ultrasound and MRI. Communication between pediatric physicians and radiologists is extremely important in minimizing radiation exposure (National Cancer Institute, 2012). The Alliance for Radiation Safety in Pediatric Imaging is a great source for physicians, medical physicists and technologists to gain knowledge on how to minimize radiation exposure on pediatric
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.
Medical imaging is very important in our present day society but how does it work? Medical imaging works with this thing called waves .Radiation in medical imaging can be very helpful to people in detecting diseases and broken bones and more faster and without a lot of this stuff many people wouldn't be here or would be walking around with a broken bone.The advancements of medical imaging has advanced a whole lot over the years so now we know a whole lot about the body.
Magnetic Resonance Imaging, or commonly known as MRI, is a technique used in medicine for producing images of tissues inside the body. It is an important diagnostic tool because it enables physicians to identify abnormal tissue without opening the body through surgery. MRI lets physicians see through bones and organs. MRI does not expose the patient to radiation, unlike tests that use X-rays. MRI provides an unparallel view inside the human body. It is the method of choice for the
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.
Medical or Diagnostic Imaging refers to the various techniques that can be used to see inside the human body. Its non-invasive nature means that the body does not have to be opened up surgically for medical practitioners to view the organs anatomically. In clinical settings, it can be used to aid in the diagnosis or treatment of different ailments. Many kinds of medical imaging techniques have already been developed, each with their own advantages
