Introduction : Most published coronary CT angiography (CCTA) studies in atrial fibrillation (AF) patients used retrospectively ECG-gated helical imaging, resulting in high radiation exposure in patients.However, the feasibility of prospectively ECG-triggered sequential acquisition has not been investigated.The purpose of this study was to investigate the feasibility of applying prospectively ECG-triggered sequential CCTA to patients with AF, and evaluate image quality and radiation dose compared with a retrospectively ECG-gated helical protocol.
