摘要：

A method of power injection of contrast material pushed with injectable saline solution during thoracic computed tomography (CT) was evaluated in 75 patients to help decrease the amount of contrast material necessary. Patients received 50-125 ml of 60% nonionic contrast material alone or pushed with 50 ml of saline. A volume of 75 ml of contrast material pushed with saline provided enhancement of the thoracic vasculature equal to that provided by a 125-mL volume of contrast material administered alone (P <.001) and caused significantly less beam-hardening artifact (P < .01).
