Towards a benchmark of abdominal CT use during duty shifts: 15-year sample from the Netherlands

Abstract Purpose To investigate temporal changes in the utilization and patient impact of abdominal CT during duty shifts in the past 15 years. Methods This study included a random sample of 1761 abdominal CT scans that were made during evening and night duty shifts in a tertiary care center between 2005 and 2019.
