Excerpt
Stress-induced myocardial perfusion defects have been firmly established as an important diagnostic and prognostic technique for identifying flow-limiting epicardial coronary artery disease (CAD). However, interpretation of such myocardial perfusion imaging (MPI) studies has been primarily qualitative or semiquantitative in nature, assessing regional perfusion defects in relative terms. Quantitative positron emission tomography (PET) measurements of myocardial blood flow (MBF) in absolute terms (milliliters per gram per minute) offer a paradigm shift in the evaluation and management of patients with CAD. The latter is concurrent with the recent shift in the management of CAD from an anatomical gold standard (i.e., coronary angiogram) to a functional one. Moreover, non-invasive quantification of MBF extends the scope of conventional MPI from detection of end-stage, advanced, and flow-limiting epicardial CAD to early stages of atherosclerosis or microvascular dysfunction and assessment of balanced reduction of MBF in all three major coronary arteries. Quantitative approaches that measure MBF with PET identify multivessel CAD and offer the opportunity to monitor responses to lifestyle and/or risk factor modification and to therapeutic interventions. …
