THE VALUE OF MAGNETIC RESONANCE IMAGING FOR EARLY DIAGNOSTICS OF PERINATAL HYPOXIC-ISCHEMIC BRAIN LESIONS

Abstract

The article presents advantages of usе the diffusion-weighted magnetic resonance imaging (DW MRI) for revealing of hypoxic-ischemic brain lesions in neonates. The trial included 105 neonates with perinatal brain lesions who had been undergoing treatment at a resuscitation department or neonatel pathology department in the first month of life. The article shows high information value of diffusion-weighted imagings (DWI) for diagnostics of hypoxic-ischemic lesions. In the event of no structural brain lesions of neonates, pronounced increase in signal characteristics revealed by DWI indicated considerable pathophysiological alterations. Subsequently, children developed structural alterations in the form of cystic encephalomalacia with the expansion of cerebrospinal fluid spaces manifested with pronounced neurological deficit.
