Ultrasonography is the primary prenatal screening modality used in the evaluation of the fetus and the maternal pelvis. However, fetal MR imaging plays a complementary role to prenatal ultrasound in the evaluation of the fetus with suspected abnormalities. MR imaging's role includes confirming or excluding possible lesions, defining their full extent, aiding in their characterization, and demonstrating other associated abnormalities. As newer techniques such as diffusion imaging, MR spectroscopy, and functional studies are used more widely, it is hoped that additional information will be made available by this modality to physicians evaluating and taking care of fetuses.
超声检查是评估胎儿和母体骨盆时使用的主要产前筛查方式。然而，胎儿磁共振成像（MR成像）在评估疑似异常胎儿时，对产前超声起着补充作用。MR成像的作用包括确认或排除可能的病变、确定其全部范围、辅助病变特征描述以及显示其他相关异常。随着扩散成像、磁共振波谱分析和功能研究等新技术的更广泛应用，希望这种检查方式能为评估和照料胎儿的医生提供更多信息。
