NUCLEAR IN THE FIELD OF MEDICINE AND HEALTH

NUCLEAR IN THE FIELD OF MEDICINE AND HEALTH
The 20th century marked a remarkable development in science and technology, including medical and healthcare disciplines and technology. This important breakthrough in science and technology makes an invaluable contribution to the diagnosis and treatment of diseases including diseases that are becoming more important epidemilogically as a logical consequence of development in all areas that have improved socioeconomic conditions of society.
The use of radioactive isotopes in medicine was started in 1901 by Henri DANLOS who used radium for the treatment of tuberculosis in the skin. But what is considered the father of Nuclear Medicine is George C. De HEVESSY, he is the principal  tracers using radioactive substances. At that time he used natural racaineotopes Pb212 .. With the discovery of artificial radioisotopes then natural radioisotopes are no longer used. An artificial radioisotope widely used in the early days of the development of nuclear medicine is I131. However, its use has now been pressed by Tc 99m in addition to its ideal nature in terms of protection and image formation can also be obtained easily and relatively cheap price. However, I131 is still indispensable for diagnostics and therapies, especially thyroid cancer gland.
The rapid development of nuclear medicine is possible thanks to the support of the development of instrumentation technology for image creation, especially with the use of computers for data processing, so that the first instrumentation system used only ordinary radiation detectors with simple electronic systems, has now developed into advanced gamma camera equipment and Positron camera that can display the image of the body tool, either two-dimensional or three-dimensional as well as static or dynamic. Today, the application of nuclear power in the field of health has made an invaluable contribution to the diagnosis and treatment of various diseases. Various medical disciplines such as internal medicine, neuroscience, cardiology, and so forth have benefited from this nuclear technique. NUCLEAR MEDICAL The medical science of   is a branch of medical science that uses an open source of radiation derived from the disintegration of artificial radionuclide nuclei, to study physiological, anatomical and biochemical changes, so that it can be used for diagnostic tangi, therapy and medical research. In nuclear medicine, radioisitop can be inserted into the patient’s body (study in-vivo) or simply reacted only with biological substances such as blood, gastric fluid, urine and so on, taken from the patient’s body better known as in-vitro studies glass experiment).

In the in-vivo study, after radioisotopes can be inserted into the patient’s body by mouth or by injection or inhaled through the nose and so the information that can be obtained from the patient can be:
1 An image or image of the patient’s organs or body parts may be obtained with the aid of a device called a gamma camera or a positron camera (imaging technique).
2 Radioisotope kinetics curves in certain organs or parts of the body and figures that describe the accumulation of radioisotopes in certain organs or parts of the body in addition to images or images obtained with positron cameras.
3 Radioactivity contained in biological samples (blood, urine, etc.) taken from the patient’s body, chopped with instruments coupled to a radiation detector (non-imaging technique). Data obtained both with imaging and non-imaging techniques provide information on the function of the organs being examined. The imaging of nuclear medicine in some hass differs from that of radiologist. (table 1) In the in-vitro study, from the patient’s body was taken a certain amount of biological material eg 1 ml of blood. Such biological material excerpts are then reacted with a substance that has been marked with radioisotopes. Examination is done with the aid of a gamma radiation detector coupled with an instrumentation system. Such studies are usually done to determine the content of certain hormones in the blood of patients such as insulin, thyroxine and others. The examination of nuclear medicine helps a lot in supporting the diagnosis of various diseases such as coronary heart disease, coronary disease
