The Use of Nuclear Medicine Radiopharmaceuticals Promises to Give Crystal Images of the Organ
In the 1980s, nuclear medicine radiopharmaceuticals were designed to diagnose heart disease. They have such property that allows nuclear medicine to image the extent of a disease-process in the body. In some cases, nuclear medicine studies can identify medical problems at an earlier stage that other diagnostic tests.
Radiopharmaceuticals are some specific substances used in nuclear medicine to diagnose or prevent disease. These drugs are made up of two components such as radioactive isotopes that can be injected into the body, and a carrier molecule which delivers the isotope to the area to be treated. There is one popular nuclear ingredient called technetium (Tc), which is used in a variety of nuclear tests. Thallium-201 is used for cardiac stress tests and some other common nuclear components in radiopharmaceuticals are indium-111, iodine-123, venom-133, gallium-67, and iodine-131.
When these nuclear medicine pharmaceuticals are injected into the body, they emit a particular radioactive signal which can be traced with special cameras. With the amount of radiation, a patient is subjected to the normal x-ray. Under the non-nuclear diagnostic method like x-rays and ultrasounds physicians can view the size and shape of a bone, tumor and organ. Once radiopharmaceuticals enter the body and travel to an organ, they start to interact with the processes of that organ. Nuclear medicine can display how the process of glucose metabolism is functioning in the body organ.
Probably, nuclear medicine tests differ from most other imaging modalities that can show the physiological function of the system being investigated. There are two most commonly nuclear imaging equipments such as Position emission tomography (PET) and Single emission computerized tomography (SPECT) scan that can create cross-sectional images of the area taken under study.
