Characterization of 3-Dimensional PET Systems for Accurate Quantification of Myocardial Blood Flow

Three-dimensional (3D) mode imaging is the current standard for PET/CT systems. Dynamic imaging for quantification of myocardial blood flow with short-lived tracers, such as ⁸²Rb-chloride, requires accuracy to be maintained over a wide range of isotope activities and scanner counting rates. We proposed new performance standard measurements to characterize the dynamic range of PET systems for accurate quantitative imaging. METHODS: ⁸²Rb or ¹³N-am…
