To investigate the effect of 3.0T MRI and ultrasonography in the diagnosis of uterine scar pregnancy (CSP) after caesarean section, and to compare their diagnostic value for CSP.
A retrospective analysis was conducted on 60 patients with CSP treated in our hospital over a period of July 2018 to March 2020. All patients underwent 3.0T MRI, ultrasonography, and surgical termination of pregnancy and pathological analysis. The value of 3.0T MRI and ultrasonography in the diagnosis of CSP was analyzed.
(1) The 60 patients were pathologically analyzed. Among these patients, 2 of whom were trophoblastic diseases, 5 were pregnancy abortion, 8 were cervical pregnancy, and 45 were CSP. (2) The results of ultrasound detection were 37 cases of CSP, 7 cases of misdiagnosis, and 8 cases of missed diagnosis; 3.0T MRI results were 44 cases of CSP, 1 case of misdiagnosis, and 1 case of missed diagnosis. (3) The sensitivity (97.78%), specificity (93.33%), coincidence rate (96.67%), positive diagnosis rate (97.78%), negative diagnosis rate (93.33%), AUC (0.973), and 95% CI (0.914-0.996) of 3.0T MRI in diagnosing CSP were significantly higher than those of ultrasound diagnosis (82.22%, 53.33%, 84.09%, 84.09%, 50%, 0.681, 0.051-0.776) (P<0.05).
The coincidence rate of 3.0T MRI in the diagnosis of CSP after caesarean section is significantly better than that of ultrasound diagnosis, and it can be used to provide reference for clinical diagnosis of CSP after cesarean section.
探讨3.0T磁共振成像（MRI）与超声检查在剖宫产术后子宫瘢痕妊娠（CSP）诊断中的作用，并比较二者对CSP的诊断价值。
回顾性分析2018年7月至2020年3月在我院接受治疗的60例CSP患者。所有患者均接受3.0T MRI、超声检查、手术终止妊娠及病理分析。分析3.0T MRI与超声检查对CSP的诊断价值。
（1）对60例患者进行病理分析。其中，2例为滋养细胞疾病，5例为妊娠流产，8例为宫颈妊娠，45例为CSP。（2）超声检查结果显示，CSP 37例，误诊7例，漏诊8例；3.0T MRI结果显示，CSP 44例，误诊1例，漏诊1例。（3）3.0T MRI诊断CSP的灵敏度（97.78%）、特异度（93.33%）、符合率（96.67%）、阳性诊断率（97.78%）、阴性诊断率（93.33%）、曲线下面积（AUC，0.973）及95%可信区间（CI，0.914 - 0.996）均显著高于超声诊断（82.22%、53.33%、84.09%、84.09%、50%、0.681、0.051 - 0.776）（P<0.05）。
3.0T MRI诊断剖宫产术后CSP的符合率显著优于超声诊断，可为剖宫产术后CSP的临床诊断提供参考。
