Establishment of diagnostic reference levels in cardiac computed tomography [PDF]
Journal of Applied Clinical Medical Physics, 2019 AbstractThe aim of this study was to determine diagnostic reference levels (DRLs) for cardiac computed tomography (CCT) in Jordan. Volume computed tomography dose index (CTDIvol) and dose–length product (DLP) were collected from 228 CCTs performed at seven Jordanian hospitals specialized in cardiac CT.
