目的初步探讨MSCT下腔静脉直接成像的优越性.方法回顾性分析本院2007年7月至2009年3月期间,28例行MSCT增强扫描的患者资料,其中2例同时行间接成像和直接成像,得到间接法下腔静脉成像10例,下腔静脉直接成像20例.采用双盲法对2种方法得出的下腔静脉图像按照图像质量和血管显示程度进行评价.结果 10例下腔静脉间接成像中,1例由于静脉期对比剂浓度太淡而失败.图像质量评价为良者2例,差者为7例,无评价为优者.20例下腔静脉直接成像中,血管显示分度为1度、2度、3度者分别为16、4和0例,图像质量为优、良、差和失败者分别为16、4、0和0例.检查成功率为100%,能较好的满足诊断要求.结论下腔静脉直接成像图像质量明显优于下腔静脉间接法得到的图像.

Objective To investigate the superiority of direct multi-slice spiral CT venography in inferior vena cava. Methods Twenty-eight patients performed MSCT venography in inferior vena cava, including 2 cases with both indirect and direct venography, 10 cases with indirect venography, 20 cases with direct venography through unilateral or bilateral lower extremity venous injection. The image quality and enhancement degree of the inferior vena cava were compared in double-blind method. Results Of 10 cases with indirect venography of inferior vena cava, 1 case was failed due to mild enhancement in inferior vena cava. Image quality was good in 2 cases, poor in 7 cases, no excellent case. Of 20 cases with direct venography of inferior vena cava, the enhancement degree was scored 1, 2 degree in 16, 4 cases respectively and no case was scored 3 degree, the image quality was excellent, good in 16, 4 cases and no case was bad. The success rate was 100%. Conclusion The image quality of direct MSCT venography in inferior vena cava is better than that of indirect method.
