Aspects IRM de l'encéphalopathie anoxo-ischémique du nouveau-né Ã terme et du prémature

These past few years have seen an increasing role of MRI in the investigation of neonatal cerebral anoxic-ischemic pathology. This is due not only to greater precision in diagnosing lesion extension, but also to earlier detection of lesions with the diffusion of weighted imagery. The aim of this iconographic review is to illustrate the main MRI aspects of anoxic-ischemic encephalopathy in a pedagogical way. After a brief physiopathology reminder, the different cerebral lesions are studied in a first chapter on the premature newborn pathology and a second chapter on full-term newborn pathology.
