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.

CMS has more than doubled the CCTA payment rate from $175 to $357.13. The move, expected to have a significant impact on the utilization of cardiac CT, received immediate praise from imaging specialists.

The newly cleared offering, AutoChamber, was designed with opportunistic screening in mind. It can evaluate many different kinds of CT images, including those originally gathered to screen patients for lung cancer. 

AI-enabled coronary plaque assessments deliver significant value, according to late-breaking data presented at TCT. These AI platforms have gained considerable momentum in recent months, receiving expanded Medicare coverage in addition to a new Category I CPT code.
