A small but growing number of doctors are using the science of sound to take a peek inside a patient’s arteries so they’ll know whether they’re at risk of a heart attack or stroke.
High-frequency sound waves produced by handheld ultrasound devices allow doctors to see inside the carotid arteries that are responsible for delivering blood to the brain. The technology offers a painless real-time view of blood flow and plaque build-up, giving a rapid assessment of disease risk.
