Diagnostic reference ranges and the American College of Radiology Dose Index Registry: the pediatric experience

Image Gently ALARA CT summit: How to Use New CT Technologies for Children

Abstract

CT scans are powerful tools used in the care of pediatric patients daily. Yet the increased use of CT warrants careful monitoring. This article defines diagnostic reference levels and how they can be used to guide practice. Once a facility has adapted its techniques and protocols to fall within diagnostic reference levels or target values, the facility can expand its quality-improvement efforts to include a new concept, diagnostic reference ranges (DRRs). DRRs take into account the subjective image quality of the examination and provide a minimum estimated patient dose, below which accurate interpretation of an image might be difficult, and an upper estimated dose, above which the patient dose may be higher than necessary. This paper also describes how the American College of Radiology Dose Index Registry can be used by a facility as a continuous quality improvement tool to monitor and manage appropriate patient dose.
