目的：探讨适合血管铸型及CT/MR扫描的填充剂配方浓度，为数字化人子宫动脉血管网模型的构建提供技术基础。方法选择三种浓度的过氯乙烯CPVC(20%、15%、10%)，分别与氧化铅（5∶100、8∶100、10∶100）、钆喷酸葡胺Gd-DTPA（1 mmol/L、2 mmol/L、5 mmol/L、10 mmol/L、15 mmol/L）及甘油（20%）进行填充剂的配制，分别经CT/MR扫描并观察其显影效果，以选择最佳显影的填充剂浓度。结果不同配方及浓度的填充剂在CT及MR显影有差异。结论以CPVC作为动脉铸型的填充剂，其中加入氧化铅（8∶100）、Gd-DTPA（10 mmol/L）及甘油（20%）行CT及MR扫描显影效果最好。

Objective To investigate the density of contrast agent which is suitable of vascular cast-ing and CT and/or MR reconstruction, then provide the basis to consteuction the digitizing human uterine artery vascular network model. Methods CT/MRI was performed using different density of contrast agent:20%, 15%, 10% of vinyl chloride respectively mixed lead oxide (5:100, 8:100, 10:100), Gd-DTPA (1 mmol/L, 2 mmol/L, 5 mmol/L, 10 mmol/L, 15 mmol/L) and glycerol (20%), choose the optimum density. Results Dif-ferent formulations and density of contrast agent in the CT and MR developing differences. Conclusions The optimum formulations and density underwent CT and MR is the CPVC, which joined the lead oxide (8:100), Gd-DTPA (10 mmol/L) and glycerol (20%).
