To assess whether a convolutional neural network (CNN) can be trained via transfer learning to accurately diagnose germinal matrix hemorrhage-intraventricular hemorrhage (GMH-IVH) on cranial ultrasound (CUS) by comparing its performance to that of a board-certified radiologist. Secondary endpoints will include the ability of CNN to grade GMH-IVH severity, identify GMH-IVH on MRI, and assess low-grade GMH-IVH on CUS that cannot reliably be seen by a radiologist. Read More

Before the germinal matrix (GM) begins to recede at approximately 26 weeks gestational age (GA), it extends along the floor of the lateral ventricles far posterior to the thalamocaudate grooves. As extremely premature infants (EPIs) as young as 23 weeks GA survive with current advances in neonatology support, germinal matrix hemorrhage (GMH) can occur along these sites from which the GM has not yet involuted and should be recognized. Further, such Grade I posterior GMH may be mistakenly diagnosed as an intraparenchymal grade IV event, particularly on coronal US or other axial images, with parasagittal images demonstrating the correct diagnosis. The aim of this study is to document and describe this phenomenon, differentiate it from traditional GMH findings, and assess its prevalence in this population. Read More

Head ultrasound (US) remains the primary screening tool for intracranial pathology in premature infants, most notably germinal matrix hemorrhage. Advances in neonatal medicine have improved survival rates of infants born at 22 to 25 weeks’ gestation. These infants demonstrate unique developing anatomy when compared to premature infants of more advanced gestational ages. Infants delivered between 20 weeks/0 days and 25 weeks/6 days of gestation have been defined as ‘periviable births’ by the American College of Obstetricians and Gynecologists. To date there is no dedicated literature describing head US findings in this population. The purpose of this review is to describe normal anatomy and pathology in the periviable population on head US. Read More

In this educational exhibit we will present a series of neonatal head ultrasound cases from our institution and present the correlative magnetic resonance imaging (MRI) which followed. We will describe a wide variety of pathologies that are often encountered but under-reported. We will also review imaging pitfalls encountered when interpreting neonatal head ultrasound and provide suggestions on how to improve the quality of these challenging examinations. Read More
