Pulmonary Venous Anatomy Imaging with Low-Dose Prospectively ECG-Triggered High-Pitch 128-Slice Dual Source Computed Tomography

摘要

BackgroundEfforts to reduce radiation from cardiac computed tomography (CT) are essential. Using a prospectively triggered, high-pitch dual source CT (DSCT) protocol, we aim to determine the radiation dose and image quality (IQ) in patients undergoing pulmonary vein (PV) imaging.
