![]() Understand how CT technical parameters, as well as nontechnical factors, affect radiation dose output.Describe common dose metric standards and measurements for CT imaging.Dose reduction and monitoring software for CT will also be discussed, as well as an overview of the regulatory, accreditation, and advisory groups that govern CT radiation dose.Īfter reading this article, the participant should be able to: This article describes current concerns related to CT radiation dose exposure, how CT dose metrics and parameters affect radiation output, and recommended radiation dose thresholds. Today, one of the highest priorities on many hospital agendas is to achieve improved control of patient radiation exposure in CT and other diagnostic imaging modalities. Although there are many benefits of using CT as a diagnostic, interventional, or therapeutic tool, concerns regarding the risks and potential long-term effects associated with increased patient radiation dose continue to emerge. It has dramatically changed how clinical diagnosis is correlated or ruled out. ![]() Computed tomography (CT) is a remarkable diagnostic tool for performing imaging studies across all age groups and anatomic regions of the body.
