Ultrasound is the imaging modality of choice for pregnant patients. However, MRI is increasingly utilized in patients in whom the sonographic diagnosis is unclear. These include maternal conditions unique to pregnancy such as ectopic pregnancy, placenta accreta, and uterine dehiscence. MRI is also being increasingly utilized in the assessment of abdominopelvic pain in pregnancy, in particular in assessment for appendicitis. Fetal MRI is performed to assess central nervous system (CNS) abnormalities and patients who are considering fetal surgery for conditions such as neural tube defects, congenital diaphragmatic hernia, and masses that obstruct the airway. In the future, functional MRI and fetal volumetry may provide additional information that can aid in our care of complicated pregnancies.
超声是孕妇首选的成像方式。然而，对于超声诊断不明确的患者，磁共振成像（MRI）的应用越来越多。这些情况包括妊娠特有的母体疾病，如异位妊娠、胎盘植入和子宫破裂。MRI在评估孕期腹盆腔疼痛，尤其是阑尾炎评估中也越来越多地被使用。胎儿MRI用于评估中枢神经系统（CNS）异常，以及那些考虑对神经管缺陷、先天性膈疝和气道梗阻性肿块等疾病进行胎儿手术的患者。未来，功能MRI和胎儿容积测量可能会提供更多信息，有助于我们对复杂妊娠的处理。
