To retrospectively evaluate the integration of pelvic computed tomographic (CT) angiography into the thoracoabdominal CT examination of blunt trauma by using 64-detector row CT to differentiate active arterial from active venous hemorrhage. ⋯ With use of 64-detector row scanning, pelvic CT angiography was successfully integrated into the authors' CT protocols and enabled differentiation between active arterial and active venous hemorrhage, which may influence clinical management.

To prospectively evaluate, in a phantom, the dose reductions achievable by using angular beam modulation (ABM) during computed tomographic (CT) fluoroscopy-guided thoracic interventions. ⋯ ABM leads to significant dose reductions for both patients and personnel during CT fluoroscopy-guided thoracic interventions, without impairing image quality.
