Management of radiation dose in cardiac CT

Abstract

Cardiac computed tomography (CCT) has beenne of the major innovations in diagnostic medicine over the past 10 years [1]. Technological developments have seen rapid evolution of scanner design and potential since the early days of 4-slice scanners. Radiation dose has been for several years a limitation of CCT (Tables 26.1, 26.2) [2]. Currently we are seeing the complete implementation of low radiation dose CCT [3-5]. One of the main issues of CCT which has thus far limited the widespread application of this modality is fading out. At the same time clinical applications are expanding together with reliability [6-9].
