Material and methods
Between January in 2016 and March in 2017, consecutive 114 patients who had abdominal hematoma for traumatic abdomen injury on MDCT at single tertiary trauma center were enrolled in this study. Each CT diagnosis was independently conducted by three radiologists. Statistical analyses were performed to compare diagnostic performance and confidence of active bleeding. Data were stratified according to each CT phase; arterial, portal venous, and combined phases and compared by two phases among...

Results
The pooled area under the receiver operating characteristics curves for the diagnosis of active bleeding ranged from 0.910 to 0.922 at each and combined phases. There was no statistically significant difference in diagnostic performance between any combination of two protocols among three protocols. The estimated mean LARs for cancer incidence were 0.059%, 0.062% and 0.121% during arterial, portal venous and combined phase, respectively.

Conclusion
Single phase CT could be the potential protocol for the diagnosis of active bleeding in abdominal trauma patients. And, use of single phase CT could decrease a sizeable number of radiation-associated cancer incidence in the future.

Purpose
The aim of this study is to compare the radiologic diagnostic performance and confidence of arterial phase, portal venous phase and combined phase in multi-detector computed tomography (MDCT) for traumatic abdominal injury.
