Abstract：
UNASSIGNED: This study aimed to compare the ultrasound (USG) and fetal magnetic resonance imaging (MRI) findings in the evaluation of congenital fetal anomalies and to determine whether the management is changes significantly if MRI is combined with USG.
UNASSIGNED: In this prospective observational cohort study, we performed fetal MRI in 90 consecutive cases of fetuses diagnosed or suspected as having congenital anomalies on a prior level II USG scan. We then compared the USG and MRI findings of each anomaly according to the diagnostic information yielded by each modality.
UNASSIGNED: Of 90 fetuses examined during 1 year study period, MRI and USG findings were equivalent in 13.3% of cases. MRI provided additional information in 68.8% cases, of which pregnancy management was changed in 5.6% cases. MRI provided additional information but did not change management in 63.3% of cases. USG provided additional information but did not change pregnancy management in 17.8% of cases. The difference was statistically significant with a p value of .000.
UNASSIGNED: Fetal MRI is a significantly better modality than USG for detecting additional findings in anomalies of specific organ systems. Because of its high diagnostic yield for central nervous system (CNS) anomalies, it can be combined with USG for this subgroup. For non-CNS anomalies of genitourinary system, thorax, or in syndromic/complex malformations/conjoint twin pregnancy, it may be used as an adjunct to USG on a case to case basis. MRI has the potential to change the pregnancy management in few cases, but benefit is small to advocate a complete integration of MRI and USG for fetal anomaly scanning at present.

摘要：
■本研究旨在比较超声（USG）和胎儿磁共振成像（MRI）在评估先天性胎儿畸形中的发现，并确定如果MRI与USG联合使用，治疗是否会发生显着变化。
■在这项前瞻性观察性队列研究中，我们对90例诊断或怀疑有先天性异常的胎儿进行了胎儿MRI检查。然后，我们根据每种模式产生的诊断信息比较了每种异常的USG和MRI发现。
■在1年的研究期间检查了90个胎儿，13.3％的病例中MRI和USG检查结果相同。MRI在68.8%的病例中提供了额外信息，其中5.6%的病例改变了妊娠管理。MRI提供了更多信息，但在63.3％的病例中没有改变管理。USG提供了更多信息，但在17.8%的病例中没有改变妊娠管理。p值为.000时,差异有统计学意义。
■胎儿MRI在检测特定器官系统异常的其他发现方面明显优于USG。由于其对中枢神经系统（CNS）异常的高诊断率，它可以与USG结合使用这个子组。对于泌尿生殖系统的非中枢神经系统异常，胸部,或综合征/复杂畸形/联合双胎妊娠，它可以在个案基础上用作USG的辅助。MRI有可能在少数情况下改变妊娠管理，但目前主张将MRI和USG完全整合用于胎儿异常扫描的益处很小.
