Estimated Radiation Dose Reduction for Prospective Electrocardiography-Triggered Dual Source CT Angiography of the Thoracic Aorta using Iterative Reconstruction: A Prospective Stu…

Ziele: To prospectively investigate image quality and radiation dose reduction for prospective ECG-triggered sequential dual-source (DS) CTA using iterative reconstruction of the thoracic aorta in comparison to prospective ECG-triggered sequential dual-source (DS) CTA with standard filtered back-projection (FBP). Methode: This study was institutional review board-approved; informed consent was obtained. 260 consecutive patients referred for ECG-assisted DS CTA of the thoracic aorta were prospectively enrolled. Tube voltage was adjusted to body mass index (
