The aim of this study was to evaluate the contribution of prenatal magnetic resonance imaging (MRI) to ultrasound (US) in the prenatal diagnosis of intra-abdominal cystic masses, correlated with the postnatal diagnosis.
In this retrospective, observational study, prenatal MRI and US diagnoses were compared with postnatal diagnoses. MRI was performed in 56 fetuses with intra-abdominal cyst diagnosed by US between 2004 and 2013. Final diagnosis, revealed by postnatal evaluation, was obtained for 49 of them and was taken as the reference. MRI was evaluated as superior, equal, or inferior to US.
An accurate diagnosis was provided by US in 25 cases (51%) and by MRI in 36 out of the 49 cases (73.4%). MRI corrected the US diagnosis in 13 cases (26.5%) by providing a more precise localization or additional etiologic information. In two cases (4%), MRI wrongly changed the diagnosis correctly made by US.
Prenatal MRI better characterized the nature of abdominal cystic lesions previously diagnosed by US in 13 cases. This enhanced postnatal therapeutic planning and so improved parental counseling and pregnancy management.
本研究旨在评估产前磁共振成像（MRI）在产前诊断腹腔内囊性肿块方面对超声（US）的辅助作用，并与产后诊断进行对比。
在这项回顾性观察研究中，将产前MRI和US诊断结果与产后诊断结果进行比较。对2004年至2013年间经US诊断为腹腔内囊肿的56例胎儿进行了MRI检查。其中49例通过产后评估得出最终诊断结果，并将其作为参考标准。将MRI评估为优于、等同于或劣于US。
US在25例（51%）中做出了准确诊断，MRI在49例中的36例（73.4%）中做出了准确诊断。MRI通过提供更精确的定位或额外的病因信息，在13例（26.5%）中纠正了US诊断。在2例（4%）中，MRI错误地改变了US做出的正确诊断。
产前MRI在13例中更好地明确了先前经US诊断的腹部囊性病变的性质。这加强了产后治疗计划，从而改善了对家长的咨询和孕期管理。
