Accuracy of dual-bolus CT in the diagnosis of active arterial bleeding in adult pelvic trauma.

Both PV-CT and DB-CT demonstrate high sensitivity in the diagnosis of any active bleeding though identification of specifically arterial bleeding is lower for both scanning methods. Nevertheless, inter-observer reliability for the identification of arterial bleeding is higher for DB-CT. Multi-phase arterial and venous CT may yield better results and could be a focus for future studies.
