Selection of PET Camera and Implications on the Reliability and Accuracy of Absolute Myocardial Blood Flow Quantification.
Ran KleinRobert A deKempPublished in: Current cardiology reports (2020)
The newest PET-CT scanners using digital silicon photomultiplier technology have high absolute sensitivity (4-20%) and time-of-flight resolution (3-7 cm) which further improves image quality. The concept of "integral" noise equivalent counts (iNEC) is introduced to compare scanner count-rate performance over the wide dynamic range encountered in MBF imaging with rubidium-82. The latest-generation digital PET scanners with wide axial field-of-view and enhanced time-of-flight resolution should enable accurate quantification of MBF, without any compromise in the quality of conventional ECG-gated myocardial perfusion images.
