How do seniors react to amyloid-PET results?
October 25, 2017 -- When told that PET scans have revealed elevated levels of beta-amyloid plaque in their brains, senior citizens feel frustrated and ask for more information about their chances of developing Alzheimer's disease, according to a study published online October 23 in JAMA Neurology.  Discuss
PET study links menopausal status to Alzheimer's
October 12, 2017 -- Could menopausal status be a factor in why women are more frequently afflicted with Alzheimer's disease than men? Using PET scans, researchers at Weill Cornell Medicine and the University of Arizona Health Sciences may have found a connection. Results of their study were published online October 10 in PLOS One.  Discuss

October 6, 2017 -- Researchers from Stanford University are reporting promising early results in the development of a novel PET radiopharmaceutical designed to identify most bacterial infections. Their findings were published in the October issue of the Journal of Nuclear Medicine.  Discuss
Rad-Aid and the search for meaning in retirement
October 2, 2017 -- What do airships, 747s, William Shatner, radiology, and giving back have in common? Semiretired radiologist Dr. Sam Friedman explains how these things are all connected -- and how he found meaning as he transitions away from the daily grind as a radiologist -- in this new column.  Discuss
PET, EEG show treatment effectiveness in comatose patient
September 28, 2017 -- Imagine being able to restore consciousness to a patient who has been comatose for 15 years. French researchers succeeded in accomplishing that goal, with the help of PET and electroencephalography (EEG) to confirm the efficacy of vagus nerve stimulation, according to a study published online in Current Biology.  Discuss
