Abstract

BACKGROUND

Prenatal awareness of an anomaly ensures better management of the pregnant patient, enables medical teams and parents to prepare for the delivery, and is very useful for making decisions about postnatal treatment. Congenital malformations of the thorax, abdomen, and gastrointestinal tract are common. As various organs can be affected, accurate location and morphological characterization are important for accurate diagnosis.

METHODS

Magnetic resonance imaging (MRI) enables excellent discrimination among tissues, making it a useful adjunct to ultrasonography (US) in the study of fetal morphology and pathology.

RESULTS

MRI is most useful when US has detected or suspected anomalies, and more anomalies are detected when MRI and US findings are assessed together.

CONCLUSION

We describe the normal appearance of fetal thoracic, abdominal, and gastrointestinal structures on MRI, and we discuss the most common anomalies involving these structures and the role of MRI in their study.

TEACHING POINTS

• To learn about the normal anatomy of the fetal chest, abdomen, and GI tract on MRI. • To recognize the MR appearance of congenital anomalies of the lungs and the digestive system. • To understand the value of MRI when compared to US in assessing fetal anomalies.

摘要

背景

产前对异常情况的认识可确保更好地管理孕妇，使医疗团队和家长为分娩做好准备，并且对于制定产后治疗决策非常有用。胸、腹部和胃肠道的先天性畸形很常见。由于各种器官都可能受到影响，因此准确的定位和形态特征对于准确诊断很重要。

方法

磁共振成像（MRI）可在组织之间实现出色的区分，因此在研究胎儿形态和病理学方面，MRI 是超声（US）的有用补充。

结果

当 US 检测到或怀疑有异常时，MRI 最有用，并且当一起评估 MRI 和 US 的结果时，会发现更多的异常。

结论

我们描述了胎儿胸部、腹部和胃肠道结构在 MRI 上的正常表现，并讨论了涉及这些结构的最常见异常情况以及 MRI 在其研究中的作用。

教学要点

  • 了解胎儿胸部、腹部和胃肠道的正常解剖结构在 MRI 上的表现。

  • 识别肺部和消化系统先天性异常的 MRI 表现。

  • 理解与 US 相比，MRI 在评估胎儿异常时的价值。
