Abstract

Technical progress in computed tomography (CT) has substantially increased the clinical efficacy of CT procedures and offered promising new applications in diagnostic imaging. On the other hand, data from various national surveys have confirmed, as a general pattern, the growing impact of CT as a major source of patient and population exposure. From a radiation-hygienic point of view, it is thus necessary to optimize the medical benefit of CT examinations to patients, while strictly controlling and reducing their risk from the radiation exposure. It is the purpose of this chapter to summarize relevant dosimetric concepts for dose assessment in CT, to give an overview on the specific factors determining radiation exposure to patients in MSCT, and to provide suggestions for the optimization of MSCT protocols to balance patient exposure against image quality.
