Adenosine-induced Stress Dynamic Myocardial Perfusion Imaging With Dual-source CT

January 18, 2019 updated by: Yonsei University
This study was designed as a prospective multicenter trial to determine the accuracy of combined CT coronary angiography and perfusion imaging, specifically quantitative dynamic perfusion imaging in patients with suspicious coronary artery disease compared conventional coronary angiography and quantitative dynamic perfusion MRI as standard reference.
