Are radioactive elements used for medical diagnosis?
Radioisotopes are widely used to diagnose disease and as effective treatment tools. For diagnosis, the isotope is administered and then located in the body using a scanner of some sort. The decay product (often gamma emission) can be located and the intensity measured.
What are the medical uses of radioactive elements?
For example, technetium-99m is used to diagnose bone, heart or other organ problems. Radioactive iodine is used in imaging the thyroid gland. For therapy, radioactive materials are used to kill cancerous tissue, shrink a tumor or reduce pain. There are three main types of therapy in nuclear medicine.
What do nuclear medicine physicians do?
Nuclear medicine radiologists, also called nuclear radiologists, are physicians who use radioactive materials, called radiopharmaceuticals, to diagnose and treat disease. They employ such techniques as scintigraphy, which uses radiopharmaceuticals to produce images of the body’s organs or to visualize certain diseases.
What radioactive isotopes are used for medical treatment?
Yttrium-90 is used for treatment of cancer, particularly non-Hodgkin’s lymphoma and liver cancer, and it is being used more widely, including for arthritis treatment. Lu-177 and Y-90 are becoming the main RNT agents. Iodine-131, samarium-153, and phosphorus-32 are also used for therapy.
What is a problem commonly associated with nuclear power?
Nuclear power plants have certain advantages: No fossil fuels are burned, and there are no combustion products, such as carbon dioxide, sulfur dioxide, and so on, to pollute the environment. But two major problems are associated with nuclear power plants: accidents (safety) and the disposal of nuclear waste.
How is radiation used to detect diseases?
Since Rontgen’s discovery over 100 years ago, radiation has been used to create visual images of the inside of the body to diagnose medical conditions. Medical professionals use ionizing radiation in specific imaging procedures to help diagnose injuries or illness within the body.
How does nuclear medicine affect the environment?
“Patients who have undergone nuclear medicine therapy are admitted to AERB-approved isolation wards. Even the human waste generated by such patients is subjected to delay and decay in tanks that are tested periodically before the sewage is discharged into the public sewage system,” Kallur assured IPS.
What is the difference between nuclear medicine and radiation therapy?
Radiation is used in nuclear medicine and radiology. In nuclear medicine, radioactive materials known as radioisotopes, or radiopharmaceuticals, are introduced into the body. In radiology, X-rays enter the body from outside.
What kind of medical treatment uses radioactive materials?
About one-third of all patients admitted to hospitals are diagnosed or treated using radiation or radioactive materials. This branch of medicine is called nuclear medicine. The radioactive materials used are called radiopharmaceuticals.
How are radiopharmaceuticals given during nuclear medicine imaging?
During a nuclear medicine imaging procedure, doctors give patients radiopharmaceuticals. Depending on the type of medical examination they can be breathed in (inhaled), injected, or swallowed. Once the radiopharmaceutical is given, the patient is usually asked to lie down on a table.
Which is an example of a nuclear medicine procedure?
These procedures use radioactive materials called radiopharmaceuticals. Examples of diseases treated with nuclear medicine procedures are hyperthyroidism, thyroid cancer, lymphomas, and bone pain from some types of cancer. The amount of radioactive materials used in diagnosing illnesses depends on the needs…
How is radioactive iodine used in nuclear medicine?
Intravascular brachytherapy systems place small sources into arteries using catheters. Therapeutic nuclear medicine uses high doses of radiation from materials that are injected into or ingested by the patient. For example, radioactive iodine can destroy or shrink a diseased thyroid.
