Will the Combination of US Contrast Microbubbles and High-Intensity Focused Ultrasound Enable Noninvasive Brain Surgery?
McDannold et al have demonstrated that the administration of a microbubble-based US contrast agent reduces the acoustic power threshold required to induce lesions in rabbit brains with high-intensity focused ultrasound and that this procedure may potentially be monitored with MR thermometry.
