Cardiac Nuclear Medicine- A Useful Technology To Diagnose Heart Disease
Nuclear medicine is a special branch of medicine under which physicians use some amount of radioactive materials (radioactive isotopes) to diagnose a variety of diseases including cancer, heart disease and other abnormalities within the body. In this procedure, radionuclides are combined with other chemical compounds to form radiopharmaceuticals. These radiopharmaceuticals can localize to specific organs or cellular receptors. The same character can be found in the cardiac nuclear medicine for the treatment of cardiac disease.
This is a noninvasive treatment procedure and the medical tests by nuclear medicine help physicians to diagnose certain medical conditions. Depending on the type of nuclear medicine, it can be injected into vein, swallowed or inhaled as a gas that eventually accumulates in the organ or area of your body. Now, it renders energy in the form of gamma rays. The energy can be detected by the devices called gamma camera, and positron emission tomography (PET) scanner. These modalities work together in coordination with a computer system to scale the amount of radiotracer to produce the images and function of organs and tissues. In the same cardiac nuclear medicine provides the images of the structure and function of the heart.
There are some other imaging technologies that are being used to diagnose cardiac and other problems of body organs. The images can be superimposed with computed tomography (CT), and or magnetic resonance imaging (MRI) that is used to produce special views. These images are offering more précised information to diagnose accurately. The invention of single photon emission computed tomography (SPECT) and PET units can carry out both imaging and analysis at the same time. These technologies are rally useful and cardiac nuclear medicine has been proving good enough to diagnose heart disease.
