CENTRAL ILLUSTRATION. Diagnostic Accuracy of Computed Tomography Angiography and Dynamic Perfusion Computed Tomography for Hemodynamically Significant Coronary Artery Disease.

CENTRAL ILLUSTRATION

Coronary computed tomography angiography(CTA) and invasive angiography demonstrating moderate stenosis (arrow) in the left anterior descending coronary artery and severe stenosis (arrowhead) in the left circumflex coronary artery. Dynamic stress computed tomography myocardial perfusion imaging demonstrated corresponding perfusion defects (yellow-blue) in the apex and lateral wall, indicating inducible ischemia, as confirmed by fractional flow reserve. The bar graph below summarizes the diagnostic performance of CTA with a coronary stenosis threshold of 50% and 70% to CTA combined with perfusion imaging.
