Abstract

The field of neurovascular ultrasound is growing rapidly with new applications. While ultrasound contrast agents were initially used to overcome poor transcranial bone windows for identification of cerebral arteries, newgeneration microbubbles in combination with innovative contrast-specific ultrasound techniques now enable potential therapeutic procedures. This article will provide a review of recent and emerging developments along with patents in ultrasound technology and contrast-specific therapeutic techniques for cerebrovascular patients.
