Reston, VA (Embargoed until 6:15 p.m. EDT, Tuesday, June 15, 2021) A new positron emission tomography (PET) radiotracer can detect abdominal aortic aneurysms (AAAs) and potentially predict when they will rupture, according to research presented at the Society of Nuclear Medicine and Molecular Imaging 2021 Annual Meeting. Targeting a novel biomarker associated with AAA, the radiotracer is effective both in diagnosis and in providing information to assist in the development of AAA treatments, of which there currently are none.
Washington University researchers part of team probing inflammation after heart attack
Inflammatory cells are visible as colored areas in this PET scan of a person’s torso, with brighter colors indicating denser cell clusters. A bright spot on the heart indicates that inflammatory cells are clustered around a site that has lost blood supply, causing a heart attack. An international team of researchers, including scientists at Washington University School of Medicine in St. Louis, has formed a network to study the role of inflammation in heart disease, with a goal of finding new therapies to improve recovery after heart attacks.
