A review of cranial ultrasound examinations performed on 426 newborns over a 42-month period demonstrated a predominance of left-sided germinal matrix hemorrhage over both right-sided and bilateral germinal matrix hemorrhage. Distribution of intraventricular or intraparenchymal hemorrhage did not show this pattern. The reasons for left-sided predominance of(More)
Sonographic features of agenesis of the corpus callosum and its related intracranial abnormalities are described in four patients. A brief review of clinical, radiologic, and pathologic manifestations of agenesis of the corpus callosum is presented. Both agenesis of the corpus callosum and its potentially serious associated intracranial abnormalities can be(More)
PURPOSE To assess the accuracy of hysterosonography (HSG) and its role in diagnostic confidence and therapeutic clinical decision making among referring physicians caring for patients with postmenopausal bleeding (PMB). MATERIALS AND METHODS One hundred twenty-three patients with PMB underwent transvaginal ultrasonography (US) and HSG. They were examined(More)
The authors reviewed the cranial sonographic findings in 8 pre-term neonates, each of whom had a clinical history and neurological outcome consistent with periventricular leukomalacia (PVL). Initially, echogenic intraparenchymal lesions were identified in a distinctive distribution at the external angle of the lateral ventricles, radiating anteriorly from(More)
Intracranial hemorrhage is a complication of extracorporeal membrane oxygenation for the treatment of neonatal respiratory failure. A retrospective review of 35 neonates treated with extracorporeal membrane oxygenation was performed; ten had intracranial hemorrhage. Infants with intracranial hemorrhage had lower birth weights and were gestationally younger(More)
RATIONALE AND OBJECTIVES Medical student surveys are used extensively in the development and modification of curriculum. The purpose of this study was to look at medical student surveys of a radiology lecture series, evaluating the accuracy of student perceptions of learning and factors affecting them. MATERIALS AND METHODS After a "Case of the Week"(More)
Intraoperative sonography is becoming increasingly important in neurosurgery. In this article, the authors provide step-by-step instructions, the basics of lesion localization, sonographic characteristics of the more common brain and spine lesions, and tables of references to sonographically described lesions in the literature.
Cranial sonography is an established procedure for the detection of neonatal intracranial hemorrhage. A 3 year experience in imaging such infants is reviewed. Representative examples are presented to comprehensively illustrate the spectrum of sonographic appearances of intracranial hemorrhage and its complications from the initial hemorrhage to resolution.(More)
