布-加综合征的优化CTV技术
|
摘要
目的:探讨布-加综合征的优化CTV像。方法:回顾性分析经DSA或手术确诊布-加综合征患者46例,所有患者术前均接受CTV检查,分为A、B2组,A组采值峰值,从对比剂均匀度、管壁边缘锐利度、分支/属支显示情况三个方面对图像进行评价,比较2组靶血管的CT值峰值及图像质量的差异。结果:A组靶血管CT值峰值的平均值高于B组;下腔静脉及肝静脉血管成像质量明显优于B组(P<0.05),门静脉成像质量差异无统计学意义。结论:布-加综合征优化CTV技术能够用更低剂量的对比剂、更为合适的扫描期相获得更优质的图像,扫描方案较为简便,可以在满足血管成像的同时兼顾腹部脏器的筛查。
Objective:To explore the optimized computed tomography venography(CTV) scanning scheme of Budd-Chiari syndrome,in order to use a lower dose of contrast agent,more suitable for the scanning phase to get better images. Methods:Clinical data of 46 patients with Budd-Chiari syndrome which confirmed by digital subtraction angiography(DSA) or surgery were retrospective analyzed.All patients received CTV scanning and were divided into A group and B group. Group A received the optimized CTV scanning scheme,group B received the traditional scanning scheme. The peak intensity of target vessel was measured.The image quality from the contrast agent uniformity,the edge sharpness of vessel and the branches in two groups were compared.Results:The CT average value of target vessel in group A was higher than that in group B(P<0.05). The quality of vascular imaging in group A was superior to group B in inferior vena cava and hepatic vein(P<0.05). There was no significant difference in the quality of vascular imaging in portal vein. Conclusion:Optimization of CTV technique for Budd-Chiari syndrome can be used in a lower dose of contrast agent,more suitable for the scanning phase to obtain a better image,the scanning scheme is simple and convenient,and can satisfy the venography at the same time taking into account the abdominal organs.
