Clinical Utility of Third-generation Dual-source Computed Tomography for Left Ventricular Function Analysis and Coronary Artery Evaluation with Minimal Radiation Exposure

摘要

With advances in acquisition techniques of computed tomography (CT), coronary computed tomography angiography (CCTA) has been widely used as a reliable imaging modality for assessing coronary artery disease (CAD). In addition, simultaneous left ventricular (LV) function analysis can be performed with retrospective electrocardiography (ECG) gated CT scanning, which acquires images throughout the entire cardiac cycle. However, retrospective ECG-gated CCTA has inevitable drawback of relatively large radiation exposure, which carries a potential risk for cancer induction.
