MRI在评价剖宫产瘢痕缺损中的应用

Application of MRI in the evaluation of cesarean scar defect

目的:分析剖宫产瘢痕缺损(CSD)的MRI表现及特征,探讨MRI对CSD的诊断价值.方法:回顾性分析行盆腔MRI平扫的121例女性患者的临床及影像学表现,评价CSD的特征.结果:121例中,瘢痕缺损10例(8.3%),瘢痕中位数宽度为6.45 mm,中位数深度为4.60 mm,瘢痕肌层厚度为4.29 mm,瘢痕附近总子宫肌层厚度中位数为12.11 mm.CSD的形状为裂隙状(30%,3/10)、三角状(60%,6/10)、凹陷状(10%,1/10).结论:MRI能准确定义CSD,减少或避免误诊和漏诊,为制订临床治疗方案提供科学依据.

Objective:To analyze the imaging manifestations and characteristics of MRI in cesarean scar defect(CSD),and to explore its diagnostic value in CSD.Methods:Retrospectively analyzed the clinical and imaging features of 121 female patients who underwent pelvic MRI,and evaluated the characteristics of scar defect in cesarean section.Results:Ten of 121 patients(8.3%)detected scar defects.The median width of the basement was 6.45 mm,the median depth of the niche was 4.60 mm,the remaining thickness of the uterine myometrium was 4.29 mm,and the median thickness of the total uterine myometrium near the niche was 12.11 mm.The shape of CSD was triangle(60%),linear(30%)and irregular(10%).Conclusion:MRI can accurately define the scar defect of cesarean section,reduce or basis for the formulation of clinical treatment.
