The selection of high pressure syringe parameters in contrast-enhanced spiral CT

Qiu Huai-ming

Abstract

Objective To discuss the reasonable application of high pressure syringe(HPS)parameters in spiral CT enˉhancement.Methods300case were scanned by contrast-enhanced CT with HPS and the different inject speed,total volume,scan delay time and patient's conditions were analyzed comprehensively.Results High and medium quality of contrast-enhanced images was86%and10%reprectively,only4%was dissatisfied.Conclusion Selecting the reasonable parameters(inject speed,total volume and scan delay time)would achieve satisfied contrast-enhanced images for diagˉnosis.
