“…It is a noninvasive, radiation-free, and reproducible procedure that can be performed at bedside, in the intensive care unit, and on the intubated ventilated baby. 22,23 Highresolution transducers, improvement of Doppler techniques (graded compression technique), and the use of different scanning techniques (mastoid and posterior fontanelle views) 24,25 have improved the ability to visualize structural and vascular abnormalities in the neonatal brain. 26 Ultrasound has also proven very useful for the detection of intracerebral hemorrhage such as intraventricular and periventricular hemorrhagic venous infarction and for detecting hypoxic-ischemic changes.…”

Developmental delay (DD) affects approximately 1% to 3% of all children in the United States. This diagnosis significantly impedes quality of life and full participation in the life of the family, school, and community. In this setting, the clinician's ability to detect, diagnose, and possibly treat the cause for DD in a timely manner depends on a multimodality approach to neuroimaging and a robust understanding of the various imaging algorithms aimed at determining the etiology of disease, structural and/or anatomic defects, functional activity, metabolic profiles, and genetic characteristics. Taken separately and in combination, these features are effectively depicted and analyzed using an array of brain imaging modalities: ultrasound, computed tomography, nuclear medicine, magnetic resonance (MR) spectroscopy, and a growing mix of sophisticated MR imaging (MRI) techniques, including diffusion-weighted imaging, diffusion tensor imaging, perfusion MRI, and functional MRI. Thus, equipped with these advanced imaging capabilities, pediatric neurologists and neuroradiologists are now positioned to diagnose with greater accuracy and speed; this, in turn, results in more effective treatment plans and improved patient outcomes as measured by progress in reaching developmental milestones and in ameliorating secondary conditions such as seizures, poor motor control, incontinence, and impulsivity. The purpose of this article is to present the numerous causes of pediatric DD, describe their respective neuroimaging findings, discuss various neuroimaging approaches for elucidating etiology, and offer specific guidelines for optimizing imaging results in the setting of multimodality imaging capabilities.

“…In this case, there is a direct linear relationship between CBF and mean arterial pressure. The association between the absence of CBF autoregulation and systemic hypotension has been implicated in the pathogenesis of cerebral white matter lesion (WML) and intraventricular hemorrhage (IVH) (11).…”

Abstract:Cranial Ultrasound is the most available and easily repeatable technique for imaging the neonatal brain. The quality and diagnostic accuracy depend on various factors; the suitability of the Ultrasound machine for neonatal cranial work, the use of optimal settings and probes, appropriate scanning protocols, the use of a variety of acoustic windows and last but not the least the scanning experience of the examiner. Knowledge of normal anatomy and the echogenicities of different tissues in normal and pathological situations as well as familiarity with the physiological and pathological processes likely to be encountered are vital. This paper assesses the value and appropriate use, safety and diagnostic accuracy of Ultrasound in evaluating the brain of the preterm born infants. This study group consisted of 308 preterm neonates, the gestational ages at birth ranged from 26 weeks to 34 weeks, and the birth weights ranged from 650 grams to 2250 grams, underwent cranial ultrasound in neonatal intensive care unit (NICU). 31 premature neonates were found to have PVL. Type of delivery, presence of perinatal asphyxia, gestation age and birth weight, were statistically insignificantly associated with PVL. Chorioamnionitis and neonatal sepsis and mechanical ventilation > 72 hours were the statistically significantly factors associated with PVL injury.

Cranial Doppler resistance index measurement in preterm newborns with cerebral white matter lesion

Abstract: The study showed that abnormal RI within the first 72 hours was associated with healing complications in newborn infants with cerebral WML. Abnormal RI results were not correlated with the fatal outcome. Therefore, RI is an important parameter that should be measured in newborn infants.
