Abstract As CT tests have become more common, concerns about the radiation hazards they pose have also grown. In this regard, optimizing CT radiation dosage has been a major emphasis for radiologists, referring physicians, technologists, and physicists. Dose-saving strategies are always evolving in two areas: imaging techniques and dosage management. Justifying the medical need of each scan is a crucial first step. Some basic recommendations for reducing exposure include customizing a scan for each patient, cutting down on scan duration, employing tube current modulation, minimizing tube current, minimizing tube potential, iterative reconstruction, and frequently evaluating CT results. This review article will provide an update on how to optimize CT dose in order to improve the benefit-to-risk ratio of this therapeutically useful diagnostic imaging method. This review article's goal is to provide an overview of the fundamentals of CT radiation exposure while highlighting the necessity of optimizing CT radiation doses through the use of new technologies and scanning parameter modifications.
