Evaluation of ECG-gated [C-11] acetate PET for measuring left ventricular volumes, mass, and myocardial external efficiency

摘要

Background. Noninvasive estimation of myocardial external efficiency (MEE) requires measurements of left ventricular (LV) oxygen consumption with [C-11] acetate PET in addition to LV stroke volume and mass with cardiovascular magnetic resonance (CMR). Measuring LV geometry directly from ECG-gated [C-11] acetate PET might enable MEE evaluation from a single PET scan. Therefore, we sought to establish the accuracy of measuring LV volumes, mass, and MEE directly from ECG-gated [C-11] acetate PET.
