Nuclear emission tomography in cardiology

Abstract:

ltant role because cardiac diseasse initially manifests as a set of biochemical and physiological changes, which subsequently presents the structural changes, visualized with modalities such as echocardiography, computed tomography, magnetic resonance imaging or angiography. These biochemical and physiological changes are detected by myocardial perfusion analysis, which describes the process of systemic circulation, which is responsible for transporting nutrients, carry waste products and carry hormones between the blood and the interstitial fluid. In this paper a description of the advances in nuclear emission imaging for the evaluation of blood flow in myocardial tissue is presented. This description considers the PET and SPECT modalities.
