OBJECTIVE
The purpose of our study was to determine whether fetal magnetic resonance imaging (MRI) provides additional information that might affect the obstetric management of pregnancies complicated by sonographically diagnosed fetal urinary tract anomalies.
METHODS
Fetal MRI and sonography were used to study 39 women with suspected fetal urinary tract anomalies in the second and third trimesters of pregnancy.
RESULTS
In 24 of 39 cases (61%), fetal MRI confirmed the sonographic diagnosis. In 14 cases (36%), fetal MRI modified the initial sonographic diagnosis and counseling but did not change obstetric management. In 1 case (3%), the addition of fetal MRI resulted in a substantial change in the management of the pregnancy.
CONCLUSIONS
During the second and third trimesters of pregnancy, fetal MRI showed fetal urinary tract anomalies in excellent anatomic detail. Fetal MRI is a useful complementary tool in the assessment of sonographically diagnosed fetal urinary tract anomalies. In a small percentage of cases, it can have a substantial impact on obstetric management.
目的
我们研究的目的是确定胎儿磁共振成像（MRI）是否能提供额外信息，从而可能影响对超声诊断为胎儿泌尿系统异常的妊娠的产科管理。
方法
采用胎儿MRI和超声对39例妊娠中晚期疑似胎儿泌尿系统异常的孕妇进行研究。
结果
39例中的24例（61%），胎儿MRI证实了超声诊断。14例（36%），胎儿MRI修正了最初的超声诊断及咨询意见，但未改变产科管理。1例（3%），增加胎儿MRI检查后使妊娠管理发生了重大改变。
结论
在妊娠中晚期，胎儿MRI能清晰显示胎儿泌尿系统异常的解剖细节。胎儿MRI是评估超声诊断的胎儿泌尿系统异常的有用补充工具。在一小部分病例中，它可对产科管理产生重大影响。
