ObjectiveWe assess the utility of transparent 3D reconstructed CT images for evaluation of traumatic pelvic bony injuries compared to traditional radiographs.MethodsRadiographs and 3D reconstructed CT were anonymized and randomized before review by 4 board certified physicians using a standardized questionnaire and compared to a gold-standard axial CT by a fifth board certified physician.Results49 patients were included. We found significant agreement (K=[0.5–0.92], p<0.001) and comparable accuracy (K=[0.36–0.38], p<0.02) and ghost images of radiographs and transparent 3D reconstructed CT without a difference in confidence (p=0.38).ConclusionTransparent 3D reconstructed CT images may be sufficient for pelvic trauma injury without the use of radiographs.
