Abstract: Objective To investigate a method that perfect imaging could be obtained and minimal contrast media was used. Methods The 5 cases with enhanced CT images were measured at each slice, then the Hu of aim-position was obtained and the Hu-time curve was got. At last, the valid enhanced period would be found. Results According to the experience, the enhancement threshold of aorta, portal vein and hepar were set at 70 HU. The onset and ending time of enhancement threshold were found. Conclusion The dose of contrast media should be extenuatory when new type spiral CT was operated, and the correlative parameters, such as flow rate, delay time etc. should be adjusted according to the objective condition.
