Nuclear Medicine?

Question

Can anyone tell me how the study of the atomic structure has led to the development of nuclear medicine? And what about the development and usage radioactive tracers to treat disease?

Answer 1

Nuclear medicine is a branch of medicine and medical imaging that uses the nuclear properties of matter in diagnosis and therapy. Many procedures in nuclear medicine use radionuclides, or pharmaceuticals that have been labeled with radionuclides (radiopharmaceuticals). In diagnosis, radioactive substances are administered to patients and the radiation emitted is measured. The majority of these diagnostic tests involve the formation of an image using a gamma camera. Imaging may also be referred to as radionuclide imaging or nuclear scintigraphy. Other diagnostic tests use probes to acquire measurements from parts of the body, or counters for the measurement of samples taken from the patient. In therapy, radionuclides are administered to treat disease or provide palliative pain relief. For example, administration of Iodine-131 is often used for the treatment of thyrotoxicosis and thyroid cancer.

Nuclear medicine differ from most other imaging modalities in that the tests primarily show the physiological function of the system being investigated as opposed to the anatomy. In some centres, the nuclear medicine images can be superimposed on images from modalities such as CT or MRI to highlight which part of the body the radiopharmaceutical is concentrated in. This practice is often referred to as image fusion or co-registration.

Nuclear medicine diagnostic tests are usually provided by a dedicated department within a hospital and may include facilities for the preparation of radiopharmaceuticals. The specific name of a department can vary from hospital to hospital, with the most common names being the nuclear medicine department and the radioisotope department.
Atoms become radioactive if atomc number is changed without changing atomic weight

Answer 3

nuclear drugs is an imaging technick the place short 0.5 stay radioactive isotopes are injected right into a affected person. the main straightforward isotope is Technechium yet gallium and iodine are used too. The isotope is constructive to a various molecure (like alnumen) and concentrates in somewhat some organs. A gamma digital camera is then used to image the affected person. The radioactivity provides a "image" of say hiver, lung etc desire that helps
