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.
