Stress perfusion cardiac MRI with regadenoson and gadofoveset trisodium
Background Stress perfusion cardiac MRI (CMR) with a high relaxivity blood-pool contrast agent should allow for improved quantification of myocardial perfusion and myocardium blood volume in patients with coronary artery disease (CAD). In the current study, we sought to evaluate the diagnostic performance and image quality of stress perfusion CMR using the intravascular contrast agent gadofoves...
متن کاملPrognostic value of cardiovascular magnetic resonance stress perfusion imaging in patients with atrial fibrillation
Methods 130 consecutive patients with atrial fibrillation referred for perfusion stress CMR using either adenosine or regadenoson were followed for hard cardiovascular events defined as cardiac death or non-fatal myocardial infarction (MACE). Ischemia was defined as new onset of perfusion defects in at least two myocardial segments (positive test). Multivariable Cox regressions for MACE were pe...
متن کاملInitial description of changes in wall motion parameters in normal subjects undergoing rest/regadenoson stress using a tagged MRI sequence
Background Changes in global and regional wall motion between rest and stress are important prognostic markers, uncommonly observed with vasodilator stress radionuclide myocardial perfusion imaging (MPI). Cardiac MRI (CMR) with tagging has the potential to more precisely quantify normal and abnormal ventricular wall motion responses. We herein report CMR findings in 5 very low-likelihood patien...
متن کاملRegadenoson 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 کاملTowards reliable myocardial blood-oxygen-level-dependent (BOLD) CMR using late effects of regadenoson with simultaneous 13n-ammonia pet validation in a whole-body hybrid PET/MR system
Background BOLD CMR is a non-contrast approach for examining myocardial perfusion but despite major technical advancements to date, its reliability remains weak. A key reason for this is the unpredictable cardiac motion during stress, which can lead to pronounced artifacts that confound/ mask the true BOLD signal changes during hyperemia. Recently, regadenoson has become the vasodilator of choi...
