Here are five key takeaways:
1. The researchers injected gas-filled bubbles into the bloodstream of a patient with a brain tumor, which created temporary holes in the blood-brain barrier.
2. Once the holes were created, the researchers directed ultrasound waves toward the bubbles, which compressed and expanded them.
3. These quick compressions and expansions loosened the cells of the blood-brain barrier, creating a direct path for chemotherapy drugs to enter the brain tumor.
4. Researchers emphasize this discovery may benefit other brain conditions, like treatments for Parkinson’s and Alzheimer’s.
5. Kullervo Hynynen, PhD, director of physical sciences at Sunnybrook Research Institute, developed the technology.
