[Abstract] 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 A1、A2 and B1、B2 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 A2 group was more obvious than that in B2 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.
