MRI在剖宫产切口瘢痕憩室诊断中的应用

Application of MRI in Cesarean Section Scar Diverticulum

目的探讨子宫器官轴磁共振成像(MRI)扫描在剖宫产切口瘢痕憩室(CSD)诊断中的价值。方法对35例超声提示CSD的患者行子宫器官轴MRI检查,观察CSD的形态,测量CSD上下径、左右径、深度、顶部到浆膜层距离,并与超声检查资料进行对照分析。结果矢状位T2WI观察CSD形态,三角形22例、凹陷形11例、其他2例。根据子宫器官轴位MRI扫描所得CSD上下径、左右径及深度测量值均大于超声测量值,MRI顶部到浆膜层距离小于超声测量值(均P<0.05)。结论沿子宫器官轴MRI扫描能直观显示并很好地评价CSD,为CSD的诊治提供影像学证据。

Objective To evaluate the value of magnetic resonance imaging(MRI) scan along the uterine axis in the diagnosis of caesarean scar diverticulum(CSD).Methods Totally 35 patients with CSD diagnosed by ultrasound underwent MRI scan along the uterine axis.MRI features of CSD were analyzed.The superoinferior diameter,anteroposterior diameter,depth and distance from top to serosal layer of CSD were measured,and the results were compared with ultrasonic findings.Results On sagittal T2 WI,CSD exhibited triangle shape in 22 cases,concave shape in 11 cases,and other types in 2 cases.Compared with ultrasonic measurement,MRI scan showed an increase in superoinferior diameter,anteroposterior diameter and depth of CSD and a decrease in the distance from top to serosal layer(P<0.05).Conclusion MRI scan along the uterine axis can provide visual display,accurate evaluation and imaging evidence for the diagnosis and treatment of CSD.
