RESTON, Va.—Imagine a new world of detecting and diagnosing diseases sooner—even before any symptoms are present. Consider the possibility of receiving individualized, targeted molecular, cellular or genetic medical treatment as soon as possible and of undergoing scanning that can quickly tell your doctor whether your treatment is working. Continued advances in positron emission tomography (PET) imaging are key to this future, according to Simon R. Cherry, professor of biomedical engineering at the University of California, Davis.
