In simple words: This is a special type of heart scan that uses two radioactive materials to take detailed pictures of your heart muscle. It shows how well blood flows to and from the heart, how well the heart muscle uses energy, and how well the heart pumps.A regular CT scan is also done at the same time to help see the heart's structure. This combined scan helps doctors figure out if the heart is healthy or if there are any problems.

Myocardial imaging, positron emission tomography (PET), combined perfusion with metabolic evaluation study (including ventricular wall motion[s] and/or ejection fraction[s], when performed), dual radiotracer (e.g., myocardial viability); with concurrently acquired computed tomography transmission scan. (CT performed for other than attenuation correction and anatomical localization is reported using the appropriate site specific CT code with modifier 59)

Example 1: A patient with a history of coronary artery disease undergoes this scan to assess myocardial viability before a planned revascularization procedure., A patient experiencing chest pain and shortness of breath undergoes this scan to evaluate for myocardial infarction and assess the extent of damage., A patient with suspected heart failure undergoes this procedure to assess both the perfusion and metabolic function of the heart muscle, along with measurements of ejection fraction and wall motion.

Documentation should include the medical necessity for the procedure, the type and dose of radiotracers used, the results of the scan, including ejection fraction and wall motion if performed, and the interpretation of the findings by a qualified physician.

** Ejection fraction (EF) is the percentage of blood pumped out of a filled ventricle with each heartbeat.A normal left ventricular EF is generally considered to be between 50% and 70%, although values can vary slightly depending on the source. An EF below 40% may suggest heart failure.This test helps assess both perfusion (blood flow) and metabolic function of the heart muscle, providing a comprehensive evaluation of heart health.
