摘　　要：目的探索宫颈癌患者盆腔脏器亚毫米CT静脉成像的最佳时间,为CT诊断及三维重建提供实践基础。方法将45名不同期别宫颈癌患者随机分为3组,每组15人,自注射造影剂起分别延时70s(A组)、90s(B组)、120s(C组)进行扫描。所得图像由两位放射科医师分别在诊断工作站进行观察,并对图像质量进行评级和评分。对评级评分数据进行统计学分析。结果各组宫颈癌患者静脉期扫描图像评价中B组总体评分最高,增强扫描后经统计学分析,三组延迟增强扫描效果均有统计学差异,B组图像整体增强效果最佳。结论自注射造影剂起延时90s行静脉期扫描,可获得图像质量最好的扫描数据,从而有利于宫颈癌的诊断及为三维重建提供实践基础。Objective To obtain the best vein scanning time of pelvic organs, and high-quality images to provide data for 3D reconstitution. Method Determination of best venous phased scanning time of pelvic CT： 45patients were divided randomly into three groups, 15 in each group, based on different delay time after injection of contrast media, 70s （group A）, 90s （group B）, 120s （group C）. Images were evaluated and graded by two experienced radiologists. SPSS13.0 software was used to process the data. Results In group B, total score was the highest. Statistic analysis of enhanced scanning data revealed that there were significant difference in image quality among the three groups after enhanced scanning and image quality in group B showed best effect of enhancement. Conclusion Delayed time of 90s after injection of contrast media is the best time of venous phased scanning, which provide the best image data for diagnosis of cervical cancer and 3D reconstitution.
