Scientist takes aim at tumors with ultrasound, magnets and microbubbles

A biomedical engineer at the University of Oxford has developed a way to finely target tumors, and only tumors, using drug-delivering microbubbles activated by ultrasound and magnetic fields. Her work has caught the eye of Wired UK.

Eleanor Stride, PhD, hopes the technique will come to supplant conventional chemotherapy, eliminating the side effects it causes with its blunt, body-wide attacks.

“[W]e’ve developed arrays of multiple magnets that allow us to trap bubbles within a specific region at depths of a few centimeters,” Stride explains. “These are in the form of small handheld devices that will be positioned at the appropriate location outside the body to accumulate the required concentration of bubbles over the course of a few minutes.”

Then comes the ultrasound, which prompts the bubbles to release the drug inside the tumor.

A total of 16 cardiology practices from 12 states settled with the DOJ to resolve allegations they overbilled Medicare for imaging agents used to diagnose cardiovascular disease. 

CCTA is being utilized more and more for the diagnosis and management of suspected coronary artery disease. An international group of specialists shared their perspective on this ongoing trend.

The new technology shows early potential to make a significant impact on imaging workflows and patient care.
