White–gray matter echogenicity ratio and resistive index: sonographic bedside markers of cerebral hypoxic–ischemic injury/edema?

Abstract

Objective:Head ultrasonography (HUS) is a reliable and easy to perform bedside imaging technique that can give valuable information about degree of brain injury/edema after perinatal asphyxia in term neonates. The goals of our study were to determine whether semiquantitative markers such as standardized white matter/gray matter (WM/GM) echogenicity ratio… (More)
