Diagnostic performance of coronary computed tomography (CT) angiography without electrocardiographic (ECG)-gating: comparison with invasive coronary angiography
ECG-less CCTA achieves high diagnostic concordance with ICA for obstructive CAD, demonstrating excellent specificity/NPV across analysis levels. Its tolerance to variable HRs and streamlined workflow support clinical utility in emergency settings or arrhythmic patients, avoiding ECG dependency and β-blockers.
