ABSTRACT

The non invasive cardiovascular imaging study consists in the combination of two technologies that are: Positron emission tomography and multi-layer computed tomography, its acronym is PET-CT. This is an imaging method used to detect, oncological, cardiac, renal and neurological alterations. It also allows evaluating the anatomy and physiology of the affected organs in one single test, which combines the advantages of each technology and offers the possibility to obtaining more information. This is considered as a last generation study. The method begins with intravenous application of a small amount of a special analogous glucose derivate called fluorodeoxyglucose (FDG) to which another substance is added. The equipment visualizes in what part of the body the substance is stored and in which amount, thus allowing to detect in a precise way the anatomy, perfusion and any alteration of an organ. In the cardiology field, this technique is used mainly to ascertain myocardial perfusion. In the presence of myocardial infarction, it identifies viable cardiac tissue (residual ischemia, lesion or necrosis). Additionally, the technique provides data about the absolute quantification of epicardial coronary flow in mL per minute.
