Ultra-high-resolution photon-counting detector CT in evaluating coronary stent patency: a comparison to invasive coronary angiography

ConclusionsUHR PCD-CTA enables non-invasive assessment of coronary stent patency with high image quality and diagnostic accuracy.Clinical relevance statementUltra-high-resolution photon-counting detector CT angiography represents a reliable and non-invasive method for assessing coronary stent patency. Its high negative predictive value makes it a promising alternative over invasive coronary angiography for the rule-out of in-stent stenosis.Key Points• CT-based evaluation of coronary stent patency is limited by stent-induced artifacts and spatial resolution.• Ultra-high-resolution photon-counting detector CT accurately evaluates coronary stent patency compared to invasive coronary angiography.• Photon-counting detector CT represents a promising method for the non-invasive rule-out of in-stent stenosis.
