Methods 123 patients with no obstructive epicardial coronary artery disease, defined by coronary computed tomographic angiogram demonstrating < 30% stenosis, underwent regadenoson CMR 1st-pass perfusion imaging, using 0.05 mmol/kg gadolinium (Gd) followed by rest perfusion imaging (also 0.05 mmol/kg Gd) performed 20 minutes later. The subjects were categorized into 4 groups: normal BMI (between...
Background Cardiovascular magnetic resonance (CMR) myocardial perfusion is a well established method for detection of significant obstructive coronary artery disease (CAD). In patients with arrhythmias, standard methods using ECGgating can result in poor image quality. Additionally, with typical stress/rest protocols, a true rest state may not be achieved after administration of regadenoson. Ho...
The prospective study included 54 asymptomatic high-risk patients who underwent coronary CT angiography (CTA) and regadenoson-induced stress CT perfusion (rsCTP). Diagnostic accuracy of significant stenosis (≥50%) determination was evaluated for CTA alone and CTA + rsCTP in 27 patients referred to ICA due to the positive rsCTP findings. Combined evaluation of CTA + rsCTP had higher diagnostic a...
