摘　　要：目的 探讨Care-bolus技术不同监测层面在显示子宫内膜下强化带中的应用。材料与方法 前瞻性纳入69位受试者,将受试者随机分为A、B两组,使用Care-bolus技术,行盆腔动态对比增强磁共振成像(dynamic contrast enhanced magnetic resonance imaging,DCE-MRI)扫描。A组受试者监测腹主动脉,B组受试者监测髂内动脉。扫描完成后再根据子宫有无病灶将A、B两组分为A;、A;和B;、B;四组。评估各组数据内膜下强化带(sub endometrial enhancement,SEE)显示情况并计算显示率,测量SEE和邻近正常肌层信号值。采用卡方检验定性评估各组SEE显示率,采用独立样本t检验定量比较各组SEE与肌层的强化差异。结果 B组显示率整体比A组高,但差异无统计学意义(P>0.05),其余各组之间显示率差异均无统计学意义。SEE信号值均比肌层高,且A组整体比B组强化差异更明显,差异有统计学意义(F=1.37,P<0.05);同时有病灶组A;比B;的强化差异更大,差异有统计学意义(F=2.31,P<0.05),其余各组间差异无统计学意义。结论 DCE-MRI扫描时使用Care-bolus技术能很好地显示内膜下强化带;且监测腹主动脉比髂内动脉更优。Objective: To explore the application of Care-bolus technique at different monitoring levels in the display of sub endometrial enhancement. Materials and Methods: Sixty-nine women were prospectively collected and randomly divided into group A and group B.Pelvis dynamic contrast enhanced magnetic resonance imaging(DCE-MRI) was performed using Care-Bolus technique. The abdominal aorta in group A was monitored and the internal iliac artery in group B was monitored. After scanning, group A and group B were divided into groups A;、A;and B;、B;according to whether the uterus had lesions. The sub endometrial enhancement(SEE) display of each groups of data was evaluated and the display rate was calculated, and the signal intensity of SEE and adjacent normal muscular layers were measured. Chi-square test was used to qualitatively evaluate the SEE display rate of patients in each groups, and independent sample student test was used to quantitatively compare the differences of enhancement degree between SEE and the muscular layer in each groups. Results: There was no significant difference in the display rate among all groups. SEE signal intensity was higher than that of the adjacent normal muscle layer, and the enhancement degree of group A was more obvious than that of group B, the difference was statistically significant(P<0.05). The degree of SEE and muscular enhancement in A;group was more obvious than that in B;group,and the difference was statistically significant(P<0.05). Conclusions: The use of Care-bolus technique in DCE-MRI scan can well show the sub endometrial enhancement, and the monitoring of abdominal aorta is better than the internal iliac artery.
