 Dual-frequency Intravascular Ultrasound Helps Detect Arterial Plaque
As carotid artery plaque cannot be diagnosed by simple ultrasound, researchers from North Carolina State University and the University of North Carolina at Chapel Hill have come up with a dual-frequency intravascular ultrasound that helps detect microbubbles.

The scientists tested the device in laboratory experiments and are planning to go ahead with pre-clinical studies that will very soon clear the decks for testing on humans.

There are other methods to find out whether the plaque is "vulnerable" to embolism, including detecting microvessels that go deep inside the plaque and spot the molecular signatures of plaques that commonly disintegrate.

Both use microbubbles as contrast agents that are found out using intravascular ultrasound, but traditional ultrasound still doesn't yield the required result.
