Ultra-high resolution photon-counting detector coronary CT angiography: diagnostic accuracy in patients with high Agatston scores
Question In patients with severe coronary calcification, conventional coronary CT angiography often suffers from blooming artifacts, reducing accuracy and causing unnecessary invasive procedures. Findings Ultra-high resolution coronary angiography with photon-counting detector CT showed high sensitivity and specificity for detecting stenoses, even at Agatston scores > 3000. Clinical relevance Ultra-high resolution coronary CT angiography enables accurate noninvasive detection of stenoses in heavily calcified vessels, potentially reducing invasive coronary angiography.
