MR imaging-guided focused ultrasound has been shown to temporarily open the blood-brain barrier (BBB), which allows for more effective delivery of drugs to the brain. In order to accomplish this, researchers use a microbubble contrast agent. The microbubbles vibrate when they pass through the ultrasound beam, temporarily ...
