Establishing institutional adult computed tomography dose reference levels at a public tertiary hospital in Singapore

This study aims to establish institutional DRLs for the four most common adult CT  examinations in Department of Radiology (DoR) in Sengkang General Hospital (SKH), namely  CT Brain (non-contrast), CT Chest (contrast, single phase), CT Abdomen-Pelvis (contrast,  portal venous phase), and CT Kidney-Ureter-Bladder (KUB) (non-contrast). The primary  purpose of this study is to determine our facility’s median (50th percentile) DRL, in line with  ICRP recommendations. Our secondary aim is to compare our obtained institutional DRLs with  that of other facilities, both at a local as well as at an international level.
