Head and body computed tomography (CT) is a routinely employed diagnostic tool for the detection and diagnosis of disease processes. With the chief focus of radiation dose reduction and improvements in CT scanners, radiation dose exposure still remains an ever-increasing concern. However, scanning protocol optimization relative to body weight and scanner manufacturer still lags behind Diagnostic Reference Levels (DRL) that are set on an international scale. With the aim of evaluating the current status of DRL over time on a global scale researchers from the Faculty of Health Sciences and Saab Medical Library at the American University of Beirut and Jordan University of Science and Technology published a new systematic review entitled "National diagnostic reference levels have a lot of potential but a long way to go. A systematic review on the current status of adult diagnostic reference levels in head, chest and abdominopelvic Computed Tomography."
The study emphasized the need for an international standardization for head and body DRL establishment methods, to provide a more comparable global measurement of dose variations across CT sites as well as regular monitoring in delivered radiation dose to patients.
