Advances in image-scanning technology have led to vast improvements in fetal evaluation. Ultrasound is the primary method of fetal assessment because it is patient-friendly, useful, cost effective, and considered to be safe. Three-dimensional (3D) ultrasound can be used as an important tool for diagnostic and prognostic evaluation. Magnetic resonance imaging (MRI) is generally used when ultrasound cannot provide sufficiently high-quality images. It offers high-resolution fetal images with excellent contrast that allow the visualization of internal tissues. 3D MRI can be an important tool in the reconstruction of virtual and physical fetal models.
