General Nuclear Medicine – Safe, Effective and Painless Imaging Technique
Nuclear medicine is a branch of medical imaging that uses small amounts of radioactive material to diagnose or treat diseases in a safe and painless way. This procedure is used to identify abnormalities within the body and that too at an early stage in the progression of a disease. This early detection allows the disease to be treated soon.
In nuclear medicine procedures, pharmaceuticals are combined with radioactive materials to form radiopharmaceuticals. The radiopharmaceuticals are tested and approved by U.S. Food and Drug Administration.There are different kinds of radiopharmaceuticals available to study different body parts. These are non-invasive, painless medical tests that help doctors diagnose medical conditions.
Depending on the type of nuclear medicine the patient is undergoing, radiopharmaceuticals are introduced into the body by injection, swallowing or inhalation. The pharmaceutical part eventually gets accumulated in the specific area of the body being examined, whereas the radioactive part emits gamma rays that can be detected by a gamma camera. These gamma cameras do not transmit radiation to the patients. These cameras capture images providing details on both the structure and function of organs and tissues.
The nuclear medicine can diagnose different kinds of diseases with surgery. This imaging technique is used to determine if certain organs are functioning properly or not. This is an ideal technique to determine the bone density, blood volume of a person and to determine the presence of cancer in various parts of the body. The nuclear medicine imaging scans are performed to scan lungs, visualize heart blood flow and to evaluate bones for fractures and arthritis.
Specially trained doctors perform the nuclear medicine procedures.
