Comparison of Measures of Left Ventricular Function from Electrocardiographically Gated ⁸²Rb PET with Contrast-Enhanced CT Ventriculography: A Hybrid PET/CT Analysis

Abstract

Global LV function can be measured reproducibly from gated (82)Rb PET, using different available software products. However, underestimation of EF by (82)Rb PET, compared with CT ventriculography, is present, which is a result of underestimation of EDV from count-poor ED frames. This underestimation needs to be considered for clinical interpretation of (82)Rb PET.
