摘　　要：目的探讨MRI检查在剖宫产术后子宫瘢痕妊娠诊治中的应用价值。方法回顾性分析2017年5月~2018年12月我院收治的28例临床及超声怀疑CSP患者的临床资料,所有患者均进行了MRI检查,分析影像特征,计算MRI对CSP诊断的准确率、灵敏度、特异度以及阳性预测值、阴性预测值。结果28例患者年龄24~43岁,平均31.9岁,停经时间39~76d,血绒毛膜促性腺激素(β-HCG)阳性。术后病理证实CSP为25例,3例为宫内孕,MRI正确诊断26例,正确诊断24例CSP,MRI对CSP的诊断准确率、灵敏度、特异度、阳性预测值和阴性预测值分别为89.3%,96.0%,33.3%,92.3%,50.0%。结论MRI检查具有较高的准确型,对临床的治疗和制定手术方案具有一定的指导作用。Objective To investigate the value of MRI in the diagnosis and treatment of cesarean scar pregnancy after cesarean section.Methods A retrospective analysis of the clinical data from 28 patients with clinical and ultrasound diagnosis of suspected CSP admitted in our hospital from May 2017 to December 2018 was conducted,the image features were analyzed,and the accuracy,sensitivity,specificity,positive predictive value and negative predictive value of MRI for CSP diagnosis were calculated.Results 28 patients were 24-43 years old,with an average age of 31.9 years.The menopause time was 39-76 days,and the serum chorionic gonadotropin(β-HCG)was positive.25 cases were confirmed as CSP by postoperative pathology,3 cases were intrauterine pregnancy,26 cases were correctly diagnosed by MRI,24 cases were correctly diagnosed by CSP.The diagnostic accuracy,sensitivity,specifi city,positive predictive value and negative predictive value of MRI for CSP were 89.3%,96.0%,33.3%,92.3%and 50.0%,respectively.Conclusion MRI examination has high accuracy,and has a certain guiding role in clinical treatment and formulation of surgical plan.
