剖宫产术后瘢痕妊娠的MRI诊断应用价值

Comparative Study of MRI and Ultrasound in Diagnosing Cesarean Scar Pregnancy

目的探讨MRI在诊断剖宫产术后瘢痕妊娠(CSP)的价值。方法回顾性分析28例经临床证实的剖宫产术后瘢痕妊娠患者的超声及MRI资料,比较超声和MRI的诊断效能。结果超声检出25例子宫下段瘢痕处囊性或囊实性病变,并提示瘢痕妊娠(25/28,准确率89.3%);误诊3例(宫内妊娠2例、宫颈妊娠1例)。28例同时行MRI检查,均在子宫切口瘢痕处发现孕囊或囊实性包块,考虑瘢痕妊娠(28/28,准确率100%)。结论超声是CSP影像学检查的首选;MRI检查具有一定的特征性,可联合超声进一步提高对CSP诊断的准确性,为临床进一步治疗选择提供影像学证据。

Objective To evaluate the value of MRI in the diagnosis of cesarean scar pregnancy(CSP).Methods The ultrasonic and MRI data of 28 patients with CSP confirmed by clinic were analyzed retrospectively,the diagnostic efficacy of transvaginal ultrasound and MRI were compared.Results 25 cases were diagnosed by transvaginal ultrasound,and 28 cases by MRI.Ultrasound diagnostic accuracy rate was 89.3%,MRI diagnostic accuracy rate was 100%.Conclusion Ultrasound is the first choice for diagnosing CSP,MRI which has certain characteristics in the diagnosis of CSP can be used as a further examination method.
