Split bolus technique in polytrauma: a prospective study on scan protocols for trauma analysis

Background For the evaluation of severely injured trauma patients a variety of total body computed tomography (CT) scanning protocols exist. Frequently multiple pass protocols are used. A split bolus contrast protocol can reduce the number of passes through the body, and thereby radiation exposure, in this relatively young and vitally threatened population. Purpose To evaluate three protocols for single pass total body scanning in 64-slice...
