Purpose To investigate pediatric abdominal CT using a simplified split-bolus (Split group) contrast injection compared with a single bolus (Control group). Methods Radiation dose, image quality and diagnostic accuracy were compared. Results Split group demonstrated lower effective dose (2.46 vs. 2.85 mSv, p = 0.002) and noise levels in aorta, liver and portal vein (p < 0.001). There was one false-negative case of portal vein obliteration in the Split group. Conclusions A simple method of split-bolus intravenous contrast injection technique can provide adequate and homogeneous enhancement in pediatric abdominal CT.
