The Society of Nuclear Medicine and Molecular Imaging (SNMMI) and the American Society of Nuclear Cardiology (ASNC) have published guidelines on how to use PET imaging for the clinical quantification of blood flow. {read more here}
Using multimodality imaging to assess Fluorine-18-sodium fluoride (18F-NaF) activity could help clinicians better predict whether abdominal aortic aneurysms (AAAs) are likely to grow more rapidly and eventually rupture, researchers reported in the Journal of the American College of Cardiology. {read more here}
Researchers conducted circadian rhythm analysis in 189 participants, with an average age of 66, who volunteered for Washington University’s Knight Alzheimer’s Disease Research Center. They were given a PET scan to detect amyloid plaques in the brain, a cerebrospinal fluid test for Alzheimer’s-related proteins or a combination of the two. {read more here}
