In the featured article of the March 2017 issue of The Journal of Nuclear Medicine, researchers demonstrate that a new positron emission tomography (PET) radiotracer, gallium-68 (Ga-68)-pentixafor, can quickly and non-invasively identify life-threatening atherosclerotic plaques. The tracer binds to the CXCR4 receptor on inflammatory cells present in atherosclerotic plaques—making it possible to find and treat atherosclerosis early. {read more here}
