【摘要】 目的:探讨先天性阴道畸形及处女膜闭锁的MRI及超声影像表现,分析其特点,提高对该病的认识。方法:12例经临床证实的先天性阴道畸形和处女膜闭锁病例,对其MRI、超声影像资料进行回顾性分析,分别计算准确率,应用卡方检验统计两者准确率差异性。结果:先天性阴道畸形(7例),为副中肾管发育畸形,先天性无阴道畸形伴痕迹子宫或无子宫2例,为Mayer-Rokitansky-Kstner-Hauser(MRKH)综合征;阴道斜隔综和征2例,超声误诊1例;阴道闭锁2例,其中1例为宫颈发育不良伴阴道闭锁;阴道横隔1例;处女膜闭锁5例。MRI诊断准确率为100%(12/12),超声诊断准确率为83.3%(10/12),两者统计学无明显差异(P>0.05),但MRI检查较超声准确率高。结论:先天性阴道畸形和处女膜闭锁的MRI及超声影像表现有一定特征,超声可作为首选的筛查检查方法,进一步MRI检查可以提高诊断准确率。更多还原

【Abstract】 Objective:To approach magnetic resonance imaging(MRI)and US manifestation of congenital vagina abnormal and imperforate hymen,analysis characteristics.Methods:To analyze retrospectively MR and US manifestation of 12 female patients confirmed,we compared the differences of accuracy.On statistics,χ2-test was used.Results:Vagina abnormal(n=7)is Müllerian duct development malformation.congenital vagina abnormal or absence of uterus(n=2),i.e.Mayer-Rokitansky-Küster-Hauser(MRKH)syndrome;Vagina oblique septum(n=2),one case misdiagnosis by US;vagina atresia(n=2),one case with cervix dysplasia;vagina transverse septum(n=1);congenital imperforate hymen(n=5).Accuracy of MRI is 100%,US is 83.3%.statistically it was considered unsignificant(P>0.05),but accuracy of MRI is higher than US.Conclusion:MR and US manifestation of congenital vagina abnormal and atresia hymenalis have characteristics,US can to be first choice for screening and MRI can improve accuracy of diognosis.更多还原
