MR-guided blood-brain barrier opening induced by rapid short-pulse ultrasound in non-human primates

摘要

Opening the blood-brain barrier (BBB) with focused ultrasound and microbubbles (MBs) has potential use in non-invasive targeted therapy for central nervous system (CNS) diseases. Rapid short-pulse (RaSP) ultrasound with a microsecond sequence has been proposed as a minimally disruptive and efficient method for opening the BBB. This work aimed to test the feasibility and safety of BBB opening in a non-human primate model using combined RaSP ultrasound sequence and MBs.
