MRI: Is There a Role in Obstetrics?HIBBELN, JOHN F. MD; SHORS, STEPHANIE M. MD; BYRD, SHARON E. MDClinical Obstetrics and Gynecology: March 2012 - Volume 55 - Issue 1 - p 352–366 doi: 10.1097/GRF.0b013e3182487d04 Imaging in Obstetrics: State of the Art Abstract Author Information Magnetic resonance imaging has a complementary role in obstetrical imaging to ultrasound (US). Although US has advantages as an initial imaging technique, there are significant numbers of patients who cannot be adequately evaluated for a variety of reasons including calvarial calcification, oligoanhydramnios, or simply obesity. MR can provide additional information that cannot be obtained by US and is invaluable in central nervous system anomaly evaluation, airway management, and planning for postnatal intervention. Newer techniques established in the postnatal population such as spectroscopy, diffusion-weighted imaging, and functional imaging have future applications in the fetus.
