Nuclear Medicine Cardiology For Treatment And Diagnosis Of Cardiac Diseases

Nuclear medicine imaging is one of the medical imaging techniques that use small proportion of radioactive materials for treatment and diagnosis of various types of diseases, including many types of cancers, heart diseases and other abnormalities within the body. It is a non-invasive, painless imaging technique that helps doctors in treatment of various medical conditions. Radioactive materials called radiopharmaceuticals or radiotracers are used for imaging.

As per the medical test, the radiotracer is injected into a vein, swallowed or inhaled as a gas. Once the radiotracer gets accumulated in the site of the body being examined, it gives off energy in the form of gamma rays. This energy is detected by the gamma camera and displayed on the monitor offering details on both the structure and function of organs and tissues.

Nuclear medicine cardiology is an imaging technique used to capture images of the structure and function of the heart. Doctors use this tool to diagnose cardiac diseases to:  
  • Figure out the reason behind unexplained chest pain
  • Analyze chest pain brought on by exercise
  • Visualize blood flow patterns to the heart walls
  • Evaluate the presence and extent of suspected or known coronary artery disease.
  • Determine the extent of injury to the heart following a heart attack, or myocardial infarction.
  • Evaluate the results of bypass surgery or other revascularization procedures designed to restore blood supply to the heart.
  • Evaluate heart-wall movement and overall heart function with a technique called cardiac gating.
Nuclear medicine cardiology can be time consuming; however, the information gathered by nuclear medicine examinations is unique and invaluable. On the basis of this information, the doctors can decide the appropriate treatment.
