A ruptura da barreira hemato-medular (BSCB) pode ser alcançada com sucesso com a administração intravenosa de microbolhas e a aplicação de ultrassom focalizado de baixa intensidade (LIFU). Este protocolo detalha a abertura do BSCB usando LIFU em um modelo de roedor, incluindo a configuração do equipamento, injeção de microbolhas, localização do alvo e visualização da interrupção do BSCB.
