MRI patterns of hypoxic-ischemic brain injury in preterm and full term infants – classical and less common MR findings

摘要

Hypoxic-ischemic brain injury occurring in antenatal, perinatal or early postnatal period constitutes an important diagnostic problem in both term and prematurely born neonates. Over the past several years magnetic resonance imaging (MRI) has become relatively easily accessible in Poland. On the basis of the central nervous system MRI, the experienced radiologist are able to determine the location of the hypoxic-ischemic lesions, their extent and evolution. Therefore he can help clinicians to answer the question whether the brain damage of the newborn is responsible for its clinical condition and he can contribute to determining the prognosis of the infant’s future development. The aim of this study is to present the current knowledge of different types of hypoxic-ischemic brain lesions based on our personal experience and MR images from the archives of the Department of Diagnostic Imaging at the Institute of Mother and Child.
