Functional Assessment of Coronary Artery Disease by Myocardial Flow Reserve Versus Pressure-wire Based Assessment: A Systematic Review.
Annals of Nuclear Cardiology(2021)
摘要
Positron emission tomography (PET) permits the noninvasive quantification of myocardial blood flow (MBF). Myocardial flow reserve (MFR), calculated by dividing stress MBF by rest MBF is a reliable index for the functional information of coronary artery disease. A pressure-derived physiological index, such as fractional flow reserve (FFR) is also an important measurement. Both MFR and FFR values are used to evaluate coronary physiology; however, but they are not interchangeable because each test has certain discrepancies. In this systematic review, we provide an overview of coronary physiology with PET compared to pressure-derived physiological indices.
