Confidence in the prediction of neurodevelopmental outcome by cranial ultrasound and MRI in preterm infants. Thirty to fiftyper cent of infants with severe IVH developpost-hemorrhagic ventricular dilation(PHVD), which may stop spontaneously (non-progressive condition) or continue (progressive condition requiring intervention). In the late and moderately preterm infant, risk factors for abnormal brain imaging include lower GA, head circumference below the 3rd percentile, need for resuscitation at birth or critical care out of keeping with the usual neonatal course (e.g., need for mechanical ventilation or inotropes in the first 24 h post-birth), complicated monochorionic twin pregnancy (e.g., selective intrauterine growth restriction (IUGR) or fetal demise), and postnatal complications (particularly sepsis, necrotizing enterocolitis (NEC), major surgery, or acute clinical deterioration)[30]-[32].

Evaluation of these structures is important when skeletal dysplasia is suspected based on abnormalities of the extremities.
