Magnetic resonance imaging has potential as an imaging technique in obstetrics. Its application has been limited by the amount of image degradation that occurs as a result of fetal movement during the long imaging times. By use of a fast-scan imaging technique good images are obtained of fetal anatomy in 3 to 14 seconds per image, depending on the setting used. Different organs could be visualized by varying the setting. Magnetic resonance imaging complements the role of ultrasonography in fetal visualization. It also allows clear fetal imaging in such high-risk situations as maternal obesity and oligohydramnios, where it may be difficult to produce clear images by ultrasonography. This technique will allow wider application of magnetic resonance imaging in obstetrics and give additional information about the developing fetus.
磁共振成像在产科作为一种成像技术具有潜力。其应用一直受到长时间成像过程中胎儿运动导致图像退化量的限制。通过使用快速扫描成像技术，根据所使用的设置，每张图像可在3至14秒内获得胎儿解剖结构的良好图像。通过改变设置可以使不同器官可视化。磁共振成像补充了超声检查在胎儿可视化方面的作用。它还能在诸如孕妇肥胖和羊水过少等高危情况下实现清晰的胎儿成像，而在这些情况下，超声检查可能难以产生清晰图像。这项技术将使磁共振成像在产科得到更广泛的应用，并提供有关发育中胎儿的更多信息。
