La perturbation de la barrière hémato-épinière (BSCB) peut être obtenue avec succès grâce à l’administration intraveineuse de microbulles et à l’application d’ultrasons focalisés de faible intensité (LIFU). Ce protocole détaille l’ouverture de la BSCB à l’aide de LIFU dans un modèle de rongeur, y compris la configuration de l’équipement, l’injection de microbulles, la localisation de la cible et la visualisation de la perturbation de la BSCB.
