Ultrasound

An illustration of improved delivery of anti-cancer drugs to malignancies in the brain. On the left half, focused ultrasound agitates microbubbles, which breach the blood-brain barrier, allowing drug molecules to get through. The forces also stir interstitial fluid to circulate the drug, and they also encourage the drug to cross cell membranes more easily into tumor cells.

Buzzing Cancer Drugs into Malignancies in the Brain

As a new anti-cancer drug delivery method heads into phase I clinical trials, researchers explore the tissue-level mechanisms that make it work.
The Science of Sound, Vibration to Better Diagnose, Treat Brain Diseases

By understanding transmission of acoustic waves through microstructure in an individual’s skull, non-invasive ultrasound imaging of the brain and delivery of therapy could be possible in a greater number of people.
