Transabdominal ultrasound (US) has not proved completely reliable in Müllerian duct anomalies. One study has shown it useful in obstructed uterovaginal anomalies. We are unaware of a study that has used endovaginal ultrasound in children to investigate uterovaginal anomalies. Magnetic resonance imaging (MRI) is now gaining wide acceptance in imaging congenital abnormalities of the genital tract.
To identify the problems and potential pitfalls of using MRI to evaluate the female genital tract in paediatric patients.
A retrospective review of the MRI scans of 19 patients, aged 3 months to 19 years (mean 14 years), with uterovaginal anomalies.
The uterovaginal anomalies were categorised into three groups: (1) congenital absence of the Müllerian ducts, or the Mayer-Rokitansky-Kuster-Hauser syndrome (n = 7), (2) disorders of vertical fusion (n = 2) and (3) disorders of lateral fusion (n = 10).
MRI is a reliable method for evaluating paediatric uterovaginal anomalies, but should be analysed in conjunction with other imaging modalities (US and genitography). Previous surgery makes interpretation more difficult and, if possible, MRI should be carried out prior to any surgery. An accurate MRI examination can be extremely helpful prior to surgery and it is important for the radiologist to have knowledge of how these complex anomalies are managed and what pitfalls to avoid.
经腹超声（US）在苗勒管异常方面尚未被证明完全可靠。一项研究表明其在梗阻性子宫阴道异常中有用。我们尚未知晓有研究在儿童中使用经阴道超声来研究子宫阴道异常。磁共振成像（MRI）目前在生殖道先天性异常的成像中越来越被广泛接受。
确定使用MRI评估儿科患者女性生殖道的问题和潜在陷阱。
对19例年龄在3个月至19岁（平均14岁）的子宫阴道异常患者的MRI扫描进行回顾性分析。
子宫阴道异常分为三组：（1）苗勒管先天性缺如，即迈耶-罗基坦斯基-库斯特-豪泽综合征（n = 7），（2）垂直融合障碍（n = 2），（3）侧向融合障碍（n = 10）。
MRI是评估儿科子宫阴道异常的可靠方法，但应结合其他成像方式（超声和生殖系统造影）进行分析。既往手术会使解读更加困难，若可能，MRI应在任何手术之前进行。准确的MRI检查在手术前可能非常有帮助，放射科医生了解这些复杂异常如何处理以及避免哪些陷阱很重要。
