The effectiveness of coronary computed tomography angiography (CTA) is hindered by high coronary calcium scores, which create blooming artefacts that obscure the coronary lumen and lead to inaccurate stenosis assessments.1 Spectral CT, utilizing multi-energy CT technology, allows data acquisition at different energy levels, improving coronary artery visualization, particularly in the presence of calcified plaques.2–4 This study evaluates the accuracy of coronary CTA using spectral CT in patients…
