PET Imaging in Cardiovascular Disease
Cardiovascular imaging has rapidly grown during the last 20 years. The established gold standard invasive cardiac catheterization for documenting coronary artery disease (CAD) is increasingly challenged by noninvasive imaging technologies. In the late 1970s, Gould et al. introduced the concept of coronary flow reserve as a functional measurement for defining the hemodynamic significance of coronary artery stenosis . Functional measurements such a perfusion imaging using scintigraphic, ultrasound, and magnetic resonance (MR) techniques have enjoyed increasing clinical acceptance. Fractional pressure measurements are recognized as an important adjunct of the therapeutic decision-making process in the catheterization laboratory, reinforcing the concept of functional characterization of CAD . There is now widespread consensus that noninvasive tests provide important diagnostic and prognostic information that complements the anatomic delineation of CAD obtainable by cardiac catheterization. Most international guidelines based on evidence criteria demand the combination of anatomic and functional information for indicating coronary interventions .
