Cardiac helical CT involving a low-radiation-dose protocol with a 100-kVp setting Usefulness of hybrid iterative reconstruction and display preset optimization

摘要

To compare the radiation dose and image quality of retrospective electrocardiogram (ECG)-gated cardiac computed tomography (CT) between a 100-kVp protocol, hybrid iterative reconstruction (HIR), and display preset optimization and the 120-kVp protocol.
