Researchers in the U.K. have found a noninvasive way to identify the early stages of atherosclerosis (buildup of fatty deposits in arteries) using a safe radioactive agent and an imaging system. The findings have been published in a recent issue of the journal Nature Communications.
For the study, patients were injected with a form of sodium fluoride that acts like a radiotracer in the body. Researchers then used various imaging techniques to track the tracer as it made its way through the body.
