Question

What is an example of a "performance enhancing drugs"?

Answer 1

Nuclear medicine...: Nuclear medicine uses radionuclides for both diagnosis and treatment of diseases. One of the most common nuclear medicine treatments is the use of radioactive iodine to treat thyroid disorders such as thyroid cancer, graves' disease, or toxic multinodular goiter. Another example is zevalin (ibritumomab tiuxetan) for treatment of lymphoma.

Answer 2

Many: Nuclear medicine covers a large number of medical conditions, including diagnosis and some treatments. Scans are routinely done in for the brain, thyroid gland, parathyroid, lung, heart, liver, spleen, bone and other organs. These scans are used to diagnose multiple acute and chronic diseases. Treatment of thyroid disease and some malignancies are also performed in nuclear medicine.

Answer 3

Physiologic study: Nuclear scans involve the ingestion, intravenous injection, inhalation, subcutaneous injection , instillation into the bladder of isotopes, radiotracers, in order to define function of various organs of the body, heart, lungs, bones, liver/spleen, stomach, thyroid gland, lymph system, kidneys, bladder, brain, parathyroid gland and gall bladder. Normal values for adults and children are known.

Answer 4

Diagnose & Rx .: Using isotopes to diagnose and treat thyroid diseases as well as many disorders of the brain, heart, lungs, liver, kidneys and skeleton. Nuclear medicine focuses mostly on function whereas radiology focuses mostly on structure.

Answer 5

Diagnose and treat: Nuclear medicine docs inject small amounts of radioactivity into patients to take images and interpret them. In addition, for some conditions, larger amounts of radioactivity are used for treatment purposes.

Answer 6

RADIOISOTOPES IN MED: Nuclear medicine deals with the application of radioactive materials in the diagnosis and treatment of diseases. The doctors specialized in nuclear medicine administer radioactive material (small amount for diagnosis and large amount for treatment) to patients to diagnose cancer, infection, blood clot in lung, and functions of various organs - heart, gallbladder, kidney, thyroid, stomach etc.

Answer 7

Another answer!: I agree with the answer, but i would like to add that the radiation adminstered with one dose of the several technetium phosphates is less than that of a just x-ray. They do not make you radioactive, since most emit gamma rays that go through you. Finally, nuclear imaging is dynamic and live. You can x-ray a corpse, but you can not nuclear image them!

Answer 8

Resources: Here's a good explaination: http://goo.Gl/scqbf nuclear medicine was called that because it uses energy from the nucleus of an atom (radioactivity) to help diagnosis and treat disease. The more common term now is molecular imaging because of the complexity of issues, where more than just the atomic nucleus is used for imaging. Here's the major organization's site: http://snm.Org/.

Answer 9

Functional imaging: Nuclear medicine involves radioisotopes which are injected intravenously or subcutaneously, inhaled into lungs, ingested, or instilled into bladder. Gamma rays from isotope form images on gamma camera. Function of organs determined. Includes heart, brain, kidneys, bladder, bones, thyroid, gall bladder, lungs, liver, spleen, lymph nodes etc.Images read by doctors specializing in nuclear medicine.

Answer 10

The : The best example of how nuclear medicine is used to cure diseases is treatment of thyroid cancer or graves' disease (a form of hyperthyroidism). In both cases the goal is to destroy thyroid tissue. The thyroid gland contains a large amount of iodine which it uses to produce thyroid hormone. Once iodine is ingested, a large amount is concentrated within the thyroid gland. Nuclear medicine harnesses this principal to destroy thyroid tissue by giving the patient a radioactive form of iodine (i-131). This radioactive iodine is concentrated in the thyroid gland. The isotope primarily releases beta radiation which destroys the surrounding tissue (most of which is thyroid tissue). If there is thyroid cancer in the area, the cancer is also destroyed.

Answer 11

No problem.: Good example: radioactive iodine has been used since for over 60 years to cure people of thyroid cancer and graves' disease.

Answer 12

W/radioactive iodine: Nuclear medicine is used to cure thyroid cancer and hyperthyroidism (sometimes caused by graves disease). Radioactive iodine (iodine 131) is given orally in a capsule and is taken up by thyroid cells (including any cancerous cells which have spread to other parts of the body. The radioactivity kills the thyroid cells and is very effective. Usually only one dose is needed to cure hyperthyroidism.

Answer 13

Thyroid disease: Most radiopharmaceuticals are used for diagnosis of functional abnormalities of organs of the body eg heart, liver, spleen, skeleton, thyroid, brain, lymph nodes, kidneys, bladder etc. Hyperthyroidism or Graves disease and thyroid cancer can be treated with high doses of I131 with destruction of thyroid tissue and curing of these problems.

Answer 14

The : The most frequent disease treated with nuclear medicine is hyperthyroidism. I small quantity of radioactive iodine-131 is given orally. The iodine is selectively taken up by the thyroid gland and damages a portion of the gland. The iodine, not absorbed by the thyroid gland, is quickly excreted by the kidney. The goal of the therapy is to return the patient to either normal thyroid function or hypothyroidism which is easily treated with thyroid hormone therapy. Other conditions treated with nuclear medicine therapy are thyroid cancer and bone pain caused by prostate, breast or lung cancer. Exciting new therapies using antibodies to target cancer with radioactive antibodies are being developed. More information is available at the society of nuclear medicine web site: www.Snm.Org.

Answer 15

Mainly thyroid: Thyroid cancer and overactive thyroids are treated with radioactive iodine i131 in high dosess. Isotope ingested by patiient is absorbed from stomach and accumulated in thyroid tissue.The thyroid tissue is detstroyed. Advanced neuroblastoma, childhood cancer, is treated with i131 mibg injected iv..Tumor accumulates isotope and is destroyed. Many antibodies tagged with isotopes are being developed.

Answer 16

Mostly thyroid.: Thyroid overactivity (hyperthyroidism which may be due to graves disease) and thyroid cancer can be treated with radioactive iodine administered orally. Nuclear medicine can also be used to treat the bone pain due metastases (cancer which has spread to the bone.).

Answer 17

Nuclear : Nuclear medicine is a branch of medical imaging that uses injected or injested radioactive isotopes to make diagnoses. Unlike xray images, cts, mris, and ultrasound studies that show anatomy, nuclear medicine studies show the phyiological processes that are occurring behind the scenes. A ct might show a fluid collection, but a nuclear medicine scan using radiolabeled white blood cells can tell you whether it's infected. Ct, mri, or ultrasound might show a mass in the liver, but the radioactive sugars used in a nuclear pet scan can tell you whether it's a malignancy.

Answer 18

Nuclear : Nuclear medicine is a branch of radiology and is medical specialty. Nuclear medicine uses radioisotopes to evaluate physiological activity of both normal body organs as well as of malignancy. With a few exceptions such as the use of contrast xray, ct, us or MRI for the most part study the anatomy and anatomical changes associated with diseases. Nuclear medicine studies physiological processes. This may involve study of contraction of the heart to evaluate for cardiac dysfunction, flow of cerebral spinal fluid to evaluate for potential obstruction, contraction of the gallbladder to find out why some has abdominal pain after meals. It can also evaluate whether a tumor or growth exhibits certain aggressiveness by seeing how much sugar it takes up comparing to normal tissues and whether that growth has spread elsewhere in the body. Nuclear medicine can also be used to treat a few disease. This is particularly in thyroid diseases where iodine 131 can be used to ablate the thyroid gland and or some of the thyroid cancers. There is a subset of nuclear medicine that uses molecular imaging where a molecule is used to target a certain particle or cells in the organ or tumor.

Answer 19

Imaging physiology: Nuclear medicine is a medical specialty using radioactive drugs to image physiology, or how the body works, as opposed to imaging like x-rays, ct or mr, which image the anatomy, or structure of the body. Nm is mostly diagnostic, but can be for therapy, as in treating thyroid cancer and hyperthyroidism with radioactive iodine. Nuclear radiology is a subspecialty of radiology, similar to nm.

Answer 20

Physiologic study: Nuclear medicine involves using internal irradiation in order to define function of heart, lungs, bones, liver/spleen, stomach, thyroid gland, lymph system, kidneys, bladder, brain, parathyroid gland and gall bladder. Some isotopes are injected iv, inhaled, and some ingested. Isotopes of higher doses are used to treat thyroid diseases.Amount of irradiation controlled for individual & environment.

Answer 21

Medical subspecialty: Nuclear medicine is a sub-specialty of medicine that employs radioisotopes in the diagnosis and treatment of diseases.

Answer 22

Physiologic study: Nuclear scans involve the ingestion, intravenous injection, inhalation, subcutaneous injection , instillation into the bladder of isotopes, radiotracers, in order to define function of various organs of the body, heart, lungs, bones, liver/spleen, stomach, thyroid gland, lymph system, kidneys, bladder, brain, parathyroid gland and gall bladder. Normal values for adults and children are known.

Answer 23

See below: Nuclear medicine is a medical specialty involving the application of radioactive substances in the diagnosis and treatment of disease.

Answer 24

Molecular Imaging: The medical specialty of nuclear medicine involves the use of unsealed radioactive pharmaceuticals that can help image molecular flow throughout the body. The medical use of radiopharmaceuticals also includes the treatment of some cancers and bone pain. Nuclear medicine is separate from diagnostic radiology, which utilizes the use of external (sealed) radioactivity to image the body.
