. La-survenue-d, une transformation hémorragique est une complication potentiellement grave d'un infarctus cérébral, pouvant être aggravée par la thrombolyse. De nombreux facteurs de risque de transformation hémorragique ont été rapportés dans la littérature, mais l'apport de méthodes d'imagerie avancées fréquemment utilisée à la phase aigüe d'un infarctus cérébral
