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.
