Diagnostic performance of regadenoson stress CMR for detection of coronary artery disease
Background The diagnostic performance of cardiovascular magnetic resonance (CMR) utilizing adenosine for detection of myocardial ischemia is well established. However, adenosine requires continuous infusion, which is challenging in the CMR environment, and has frequent side effects. The diagnostic accuracy of stress CMR using regadenoson, a newer vasodilator agent that is administered as a sing...
متن کاملRegadenoson in the detection of coronary artery disease
Myocardial perfusion studies use either physical exercise or pharmacologic vasodilator stress to induce maximum myocardial hyperemia. Adenosine and dipyridamole are the most commonly used agents to induce coronary arterial vasodilation for myocardial perfusion imaging. Both cause frequent undesirable side-effects. Because of its ultrashort half-life, adenosine must be administered by constant i...
متن کاملDiagnostic performance of image navigated coronary CMR angiography in patients with coronary artery disease
BACKGROUND The use of coronary MR angiography (CMRA) in patients with coronary artery disease (CAD) remains limited due to the long scan times, unpredictable and often non-diagnostic image quality secondary to respiratory motion artifacts. The purpose of this study was to evaluate CMRA with image-based respiratory navigation (iNAV CMRA) and compare it to gold standard invasive x-ray coronary an...
متن کاملDiagnostic Accuracy of Gated-SPECT Myocardial Perfusion Imaging and Exercise Stress Test for Diagnosis of Coronary Artery Disease
Background and Objective:Accurate diagnosis of CAD using noninvasive procedures is of great importance. The aim of the study is to assess diagnostic accuracy of myocardial perfusion imaging and compare it with exercise stress test in order to decipher a more accurate and cost-effective method for CAD detection. Materials and Methods:Of 430 consecutive patients suspected with CAD, 104 performed...
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...
