Noun

2. (medicine) The use of ultrasonic waves for diagnostic or therapeutic purposes.
   • 1991, Stephen King, Needful Things:

     Ultrasound as a treatment for degenerative arthritis was in its infancy. It might eventually turn out to be as effective as the Salk vaccine, or as bogus as the science of phrenology.

It’s estimated only 0.1% of antibodies circulating in the bloodstream enter the brain – this also includes the therapeutic antibodies currently used in clinical trials. An approach my team is taking is to use ultrasound to temporarily open the blood-brain barrier, which increases the uptake of Alzheimer’s drugs or antibody fragments.
