Dose-reduction strategies in whole-body CT for injured patients in the emergency department: a scoping review

Across studies, a consistent trend of dose reduction was observed with all strategies, with larger reductions reported for split-bolus protocols. However, direct comparisons were limited by heterogeneity in study designs, scan protocols, and reporting measures of effect, precluding definitive conclusions about the relative superiority of any single approach. Image quality did not seem to be affected by dose reduction. However, there was an increase in missed diagnoses of arterial injury. Direct comparisons were limited by heterogeneity in study designs, scan protocols, and reporting measures of effect, precluding definitive conclusions about the relative superiority of any single approach.
