Stay tuned for more helpful posts like this one. Confidence in the prediction of neurodevelopmental outcome by cranial ultrasound and MRI in preterm infants. PVHI represents a venous hemorrhagic infarct in the drainage area of the periventricular terminal veins and typically leads to cystic changes in periventricular white matter (porencephalic cyst)[8]. A prospective observational study in the Journal of Ultrasound in Medicine has concluded that for pretreatment evaluation of uterine fibroids (UF), transabdominal contrast-enhanced ultrasound (CEUS) represents a viable alternative to traditional contrast-enhanced magnetic resonance imaging (MRI). Note:Data excludes moribund infants, those with major congenital anomalies, and those with no neuroimaging results. Although the heart structures aren't yet fully developed at six weeks gestation, it's possible to see the electrical impulses of their developing heart (sometimes referred to as embryonic cardiac activity). Physiologic midgut herniation is common prior to 12 weeks gestation and should not be confused with an omphalocele. 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].

As usual, youll be weighed and your blood pressure will be taken at all doctors appointments. J Pediatr. Image acquisition The detection of fetal abnormalities before 11 weeks of gestation relies not only on the experience of the operator but also on using high-resolution probes and transvaginal imaging. Intracranial hemorrhage and white matter insult are the two most significant brain injuries that can affect the preterm brain, and both are associated with adverse neurodevelopmental outcomes, including cerebral palsy (CP)[1]-[6]. "Some ultrasound findings, like an echogenic intracardiac focus (EIF) are frequently detected on ultrasound," Dr. Chao says. Make sure that you include B6 in your diet throughout the pregnancy, but mainly on the third trimester.

For extremely ill, extremely low GA (less than 26 weeks) infants, when severe bleeding or injury might inform shared decision-making with parents regarding goals and direction of care, an ultrasound in the first few days after birth may be considered. If ventricular dilatation or worsening PHVD is detected, the frequency of HUS should be intensified (at least weekly initially and as clinically indicated thereafter). Sex is assigned at birth based on the appearance of a baby's genitalia. Prakesh Shah and Priscilla Chan, from the Canadian Neonatal Network, helped provide data on the incidence of brain injury in babies < 33 weeks in Canada. Realtime scanning should evaluate the integrity of the calvarium. MRI offers the highest resolution for detecting and quantifying WMI, low grade IVH, cerebral malformation, and posterior fossa abnormalities, due to its greater neuroanatomical definition [11][33][34].

If ventricular dilation is present, the frequency of HUS should be intensified: at least weekly initially and as clinically indicated thereafter. The subependymal GM, a highly vascularized region of the brain, is extremely fragile and the primary source of bleeding within the cerebral ventricles, causing IVH. It was also reviewed and approved by the Canadian Neurological Sciences Federations Clinical Practice Guidelines Committee.

In rare cases, prenatal diagnosis can lead to fetal intervention, although most anomalies do not require any treatment in utero. A profile view can identify a small mandible, or micrognathia (Figure 4). Brain imaging performed early in life can also contribute to identify antenatal brain injury or findings in keeping with metabolic or genetic disorder.
