磁共振成像在早期宫角妊娠中的应用价值

Application of MRI in Early Cornual Pregnancy

目的探讨磁共振成像(MRI)在早期宫角妊娠中的应用价值。方法回顾性分析本院30例经临床证实的宫角妊娠患者的MRI和超声资料,观察妊娠囊的部位、大小、形态,并观察有无绒毛植入,对比两者的诊断正确率。结果超声和MRI诊断宫角妊娠准确率分别为93.3%(28/30)、96.7%(29/30),两者诊断正确率比较,经过确切概率法计算,差异无统计学意义(P=0.381);超声和MRI分别诊断合并绒毛植入的准确率分别为83.3%(25/30)、96.7%(29/30),两者诊断正确率比较,经过确切概率法计算,差异有统计学意义(P=0.007)。术前MR误诊1例为滋养细胞肿瘤。结论超声和MRI可以早期、无创、准确诊断宫角妊娠,在诊断是否合并绒毛植入及判断绒毛活性方面,MR准确率更高,能为临床判断风险和制定治疗方案提供帮助。

Objective To investigate the value of magnetic resonance imaging(MRI)in early cornual pregnancy.Methods The MRI and ultrasound data of 30 cases withcornual pregnancy in our hospital were retrospectively analyzed.The location,size,and shape of the gestational sac were observed,and the presence or absence of villous implantation was compared.Results The accuracy rates of ultrasound and MRI in diagnosing cornual pregnancy were 93.3%(28/30)and 96.7%(29/30).There was no significant difference in the diagnostic accuracy of the two(P=0.381).The accuracy of MRI in diagnosing villus implantation was 83.3%(25/30)and 96.7%(29/30).The diagnostic accuracy of the two was statistically significant(P=0.007).Onecase was misdiagnosed as a trophoblastic tumor by preoperative MR.Conclusion Ultrasound and MRI can provide non-invasive accurate andearly detection ofcornual pregnancy.MRI has higher accuracy in the diagnosis of villous implantation and defining villus activity,which can help judgment of risk and development of a treatment plan.
