Nuclear medicine as an interdisciplinary clinical branches, is an example of integration of medical and other scientific disciplines (physics, chemistry, nuclear electronics, computer science) in order to study the functions and structures of authority. Nuclear medical methods are simple, they are non-invasive, and usually do not need anything more than an intravenous injection of radiopharmaceuticals. The study was a secondary side effects very rare, negligible morbidity, and mortality does not really exist.
Contrary to the general misconception that the introduction of radioactive isotopes body irradiation causes more than transmitted radiation dose exposure of patients is usually much smaller than the imaging tests. The great advantage of nuclear medicine is that after entering the diagnostic zone, the dose of irradiation received by the patient remains the same, regardless of the number function or scintigarfskih tests should be done. This is completely contrary to radiological examinations, in which radiation dose is directly dependent on the number of diagnostic tests. For more efficient diagnostic nuclear medicine is essential that a specialist of this kind of medicine clearly understand the clinical problem, determine the reasons for testing and selecting the most appropriate diagnostic procedure. Nuclear medicine can arbitrarily be divided into diagnostic and therapeutic part. The world is evolving so rapidly that already dispersed in the level of specialization, such as nuclear cardiology, gastroenterology nuclear, nuclear endocrinology, nuclear nefrourologija, nuclear neurology, nuclear oncology and others.
According to the recommendations of major international associations of Cardiology (AHA, ACC and ASNC) is now in the U.S. before each coronary unit (where he secured admission in patients with acute myocardial infarction) is a gamma camera (the necessary equipment to perform nuclear cardiac diagnosis), with normal results myocardial perfusion enables the patient with chest pain who plays acute myocardial infarction, does not receive the korornarnu unit. Nowadays, it's clinical significance of nuclear cardiology in the world, that basically creates a way to guide clinical therapy, and to monitor therapeutic effects and its possible complications.
