Nuclear Medicine And Its Effects

Somehow not only drugs but other option to treats tumour for targeted therapy oncologist will used radiation which radioactive rays are used to cure or palliate cancers. The objective is to deliver a therapeutic dose of radiation to the malignant tissue, leaving healthy, surrounding tissues unharmed. Radiation therapy is used to treat many cancers, including cancers of bone, brain, breast, cervix, lymphoid tissues, and uterus. By then, from diagnosis through end of life, nurses play an obscure role in enhancing the quality of life of the patients especially which has undergone the treatment or newly diagnosed. Nurses are in a unique position to manipulate both the physiologic

From surgery to radium exposure to such extremes as radiation therapy, as doctors’ knowledge of the varying types of cancer, and the expansion of medical research regarding cancer has changed, so has the preferred method of treatment. Doctors and researchers dedicated to studying cancer have led to a greater understanding of cancer development; consequently the development of treatments and cures that are more effective, less harmful, have fewer side effects, and in some cases serve to prevent the spread of cancer.

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.

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.

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.

Seidlin reported on the success of radioactive iodine (I-131) in treating a patient with advanced thyroid cancer. Later, the use of I-131 was expanded to applications such as thyroid gland imaging, hyperthyroidism treatment and quantification of thyroid function. By the 1950s, the clinical use of nuclear medicine had become widespread as researchers increased their understanding of detecting radioactivity and using radionuclides to monitor biochemical processes.” (Dr. Ananya Mandal, MD) With this information, we know that nuclear medicine is successful with multiple cases of diseases. Our technology today has improved on how treatments can be done. Nuclear medicine has improved from the time being. If treating a disease with nuclear medicine back then had been successful, imagine all of the success stories of everyone today who has had the chance of using nuclear medicine. Nowadays, the science and technology has developed so much that it is easy to cure any type of disease when proper guidance is given. If the technology is used properly, the side effects can be reversed. Today, we can easily figure out a way to reverse the effects of what we did to ourselves with all of the equipment, tools, and technology that people

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.

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

Radiation therapy is the ionization of atoms in tissues resulting in formation of highly reactive radicals in a well-defined, restricted volume (1). In other words, ionizing radiations are used to eradicate tumors and at the same time preserve structure and function of normal tissue. A limitation is prevented from being a problem. If bone marrow or neuronal cells are destroyed or injured, they do not regenerate. However, with radiation therapy, these cells are often saved from injury or destruction, unless the tumor is infecting bone marrow or neuronal cells. Today, radiation therapy is the most popular type of cancer therapy in use. It is used to treat one-half to two-thirds of all cancers, which translates to more than ten percent of the population

Thus consideration of absorbed dose to minimizing dose delivery and assessment of radiation damage to bone marrow is important. To attain effective radionuclide therapy, it is essential to identify appropriate radionuclides as well as to develop better bone seeking agents that could result in good in vivo localization and desired excretion [12]. There are two major groups of radionuclides for treating painful bone metastases including, β emitting radionuclides; 32P,89Sr, 90Y, 153Sm, 166Ho, 177Lu, 186Re, 188Re and α emitting radionuclide;223Ra [13-19]. The 32P and 89Sr were the first radioisotope to be evaluated for palliative treatment of bone metastases [20, 21]. Currently, there are several commercially available β emitting radionuclides for bone pain palliation as 89SrCl2, 153Sm-EDTMP and 186Re-HDEP [22, 23]. However, another radionuclide is under research for palliative treatment of bone metastasis, such as 90Y, 166Ho, 177Lu and 188Re. Recently, 223RaCl2 that uses the bone-seeking α emitter 223Ra has become available and it approved by the FDA for clinical use in 2013 [24-27]. For each atom of 223 Ra, 4 alpha particles are released that they are representing 94 % of the total radiation energy emitted

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.

In 2007, it is predicted that almost 1.5 million people will be diagnosed with cancer in the United States (Pickle et al., 2007). More than half of these cancer patients will undergo the use of radiation as a means for treating cancer at some point during the course of their disease (Perez and Brady, 1998). Cancer, a disease caused by an uncontrollable growth of abnormal cells, affects millions of people around the world. Radiotherapy is one of the well known various methods used to treat cancer, where high powered rays are aimed directly at the tumor from the outside of the body as external radiation or an instrument is surgically placed inside the body producing a result of internal radiation. Radiation is delivered to the cancerous regions of the body to damage and destroy the cells in that area, terminating the rapid growth and division of the cells. Radiation therapy has been used by medicine as a treatment for cancer from the beginning of the twentieth century, with its earliest beginnings coming from the discovery of x-rays in 1895 by Wilhelm Röntgen. With the advancements in physics and computer programming, radiation had greatly evolved towards the end of the twentieth century and made the radiation treatment more effective. Radiation therapy is a curative treatment approach for cancer because it is successful in killing cancerous tumor cells and stop them from regenerating.

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.
