Regadenoson versus dipyridamole hyperemia for cardiac PET imaging.
OBJECTIVES The goal of this study was to compare regadenoson and dipyridamole hyperemia for quantitative myocardial perfusion imaging. BACKGROUND Regadenoson is commonly used for stress perfusion imaging. However, no study in nuclear cardiology has employed a paired design to compare quantitative hyperemic flow from regadenoson to more traditional agents such as dipyridamole. Additionally, th...
متن کاملDoes a shortened hyperemia with regadenoson stress pose a concern for quantitative Rb-82 PET imaging? Optimization of regadenoson PET imaging.
A lthough regadenoson has nearly replaced other vasodilator stressors for single-photon emission computed tomography perfusion imaging, the benefits of regadenoson stress for positron emission tomography (PET) perfusion are less clearly established, particularly in the estimation of absolute stress flow with dynamic PET imaging. In the estimation of absolute flow with dynamic PET, the timing of...
متن کاملCorrelation between hemodynamic changes and tomographic sestamibi imaging during dipyridamole-induced coronary hyperemia.
OBJECTIVES The purposes of this study were to examine the effects of dipyridamole infusion on hemodynamic variables and to compare these changes with myocardial perfusion. BACKGROUND Dipyridamole stress testing with myocardial perfusion imaging is widely used in the assessment of patients with known or suspected coronary artery disease (CAD). Few studies, however, have correlated the hemodyna...
متن کامل4D PET: Beyond conventional dynamic PET imaging
In this paper, we review novel techniques in the emerging field of spatiotemporal 4D PET imaging. We will discuss existing limitations in conventional dynamic PET imaging which involves independent reconstruction of dynamic PET datasets. Various approaches that seek to attempt some or all of these limitations are reviewed in this work, including techniques that util...
متن کاملDetection of obstructive coronary artery disease using regadenoson stress and 82Rb PET/CT myocardial perfusion imaging.
UNLABELLED Our objective was to study the diagnostic performance of regadenoson (82)Rb myocardial perfusion PET imaging to detect obstructive coronary artery disease (CAD). METHODS We studied 134 patients (mean age, 63 ± 12 y; mean body mass index, 31 ± 9 kg/m(2)) without known CAD (96 with coronary angiography and 38 with low pretest likelihood of CAD). Stress left ventricular ejection fract...
