Images provided by MRI are superior in quality and more inclusive. When the first brain imaging is abnormal (Grade 2 or higher IVH or in the presence of WMI), a repeat HUS should be performed 7 to 10 days later to detect complications, such as PHVD. Routine head ultrasound examination is recommended for all infants born at or before 31+6 weeks gestation. The test can detect about 75% of Down syndrome cases in women under age 35 and .

Severe skeletal dysplasias, such as thanatophoric dysplasia, can have features such as small limbs and narrow chest even in the first trimester. In these cases, early second-trimester ultrasound can lead to prenatal diagnosis prior to the routine 18- to 20-week scan. Evaluation of the outflow tracts, or the aorta and pulmonary artery as they exit the left and right ventricles, is recommended if possible. In isolation, brain imaging has only moderate predictive value, and multiple factors need to be taken into account when predicting neurodevelopmental outcomes (Grade B recommendation). Newer MRI classifications and scoring systems seem to yield better predictive values, but their applicability in the clinical setting remains to be determined [38][41]-[43]. The wider availability of MRI, improved ultrasound techniques, and increasing rates of survival at very low gestational ages, have changed the clinical picture. Even in cases where a small crown-rump length and a slow heart rate were present early in pregnancy, 80% of the pregnancies . Agenesis of the corpus callosum should be suspected when the cavum septum pellucidum is not visible, the third ventricle appears prominent, and the lateral ventricles have a teardrop-shaped configuration, with dilation of the posterior horns. Hydrocephalus in a male fetus with no associated finding could reflect a mutation in the L1CAM gene associated with X-lined hydrocephalus.

A first-trimester ultrasound is a valuable tool to confirm viability, rule out multiple pregnancy, and evaluate anatomy, even if genetic screening is not desired. [Review]. Such injuries include cystic and punctate lesions, delayed myelination, volume loss, thinning of the corpus callosum, and diffuse excessive high signal intensity (DEHSI)[36]. Because GMH-IVH and ischemic WMI occur more often in preterm infants (and much more often in infants born before 32 weeks GA), routine HUS examinations are most valuable for this group.
