Sažetak
Aim: To evaluate dual-energy CT (DECT) whole-body polytrauma protocols and quantify radiation dose reduction compared with a standard multiphase CT protocol.
Materials and Methods: This retrospective single-centre study included polytrauma patients, stratified into three groups: standard CT (n = 255), DECT-stable (n = 164), and DECT-unstable (n = 19). Radiation dose was assessed using the dose-length product (DLP).
Results: Median DLP was 5940 mGy·cm (standard), 2671 mGy·cm (DECT stable), and 3247.5 mGy·cm (DECT unstable), corresponding to dose reductions of 55.0% and 45.3%, respectively.
Conclusion: DECT protocols enable substantial radiation dose reduction while maintaining clinical workflow efficiency.
