Imaging in Obstetrics T2 CURRENT Diagnosis & Treatment: Obstetrics & Gynecology, 11e YR 2013 FD 2013 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-163856-2 LK obgyn.mhmedical.com/content.aspx?aid=56965495 RD 2024/10/11 AB Technology for imaging in obstetrics has advanced a great deal over the past decade, but the purpose remains the same: to evaluate the anatomy and well-being of the fetus and the mother. The primary imaging modality in obstetrics is the 2-dimensional (2D) ultrasound because it is safe and widely available. Three- and 4-dimensional (3D/4D) ultrasound and magnetic resonance imaging (MRI) are also being used in certain situations to enhance imaging techniques, but the cost of these modalities limits their widespread use. Finally, computed tomography (CT) scan has limited utility because of safety issues but may be necessary in evaluating certain maternal conditions.
