Abstract Ultrasound is still the first screening method in pregnancy and it will continue to be. Sonography remains the mainstay of fetal assessment. However, MRI of the fetal CNS is evolving as a powerful tool for obtaining additional information with which selected patients and their health-care professionals can make important management decisions. When a CNS anomaly is detected at US, MRI imaging may demonstrate additional findings that may alter patient counseling and case management. Given its long record of safety, utility, and cost-effectiveness, ultrasound will remain the modality of choice when screening the fetus. Ultrasound remains far too useful, effective, and widely available, and it also images in real time. Ultrasound is and will remain the primary fetal monitoring modality. A valuable complement to prenatal sonography, fetal MR imaging is a powerful technique used to evaluate the fetal brain. Fetal MR imaging has higher contrast resolution than prenatal sonography and allows better differentiation of normal from abnormal tissue. |
