Computed Tomography Angiography of Carotid Arteries and Vertebrobasilar System A Simulation Study for Radiation Dose Reduction

摘要

Computed tomography angiography (CTA) of carotid arteries and vertebrobasilar system is a standardized procedure with excellent image quality, but radiation exposure remains a matter of concern. The aim of this study is to examine to what extent radiation dose can be lowered in relation to a standard protocol by simulating examinations with lower tube currents applying a dedicated software.
