PURPOSE To retrospectively determine whether the combined use of automatic tube voltage selection (ATVS) and automatic tube current modulation (ATCM) can effectively reduce radiation dose at contrast material-enhanced liver computed tomography (CT) while maintaining acceptable image quality compared with the use of ATCM alone. MATERIALS AND METHODS This study was approved by an institutional review board, and informed consent was waived. Three hundred fourteen consecutive patients suspected… CONTINUE READING
