CT radiation dose tracking reveals global disparities

Tuesday, October 3, 2017

Aunt Minnie (10/3, Kim) reports that there are “substantial differences around the world in the amount of radiation dose being used for CT scans,” according to a study published online in the American Journal of Roentgenology. Swiss researchers used radiation dose-tracking software to study the amounts in select North American and European medical institutions and found that “CT dose levels measured at California hospitals and from facilities reporting to the American College of Radiology (ACR) Dose Index Registry (DIR) were up to 240% higher than the dose used at their facility, University Hospital Basel.” The piece concludes, “the inconsistency in CT radiation dose used at local neighboring facilities and the wide-ranging differences among distinct registries suggest the need for dose optimization, according to the authors.”
