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

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
