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
Novel PET tracer could identify bacterial infections
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 September 25 in Current Biology.  Discuss
PET tracks Zika virus, disease progression in mice
September 21, 2017 -- Researchers from the U.S. Army are using PET scans of mice to study brain inflammation and gather more information about the progression of disease due to the Zika virus, according to a study published online September 12 in Molecular Imaging and Biology.  Discuss
FDG-PET/CT contributes to anal cancer follow-up
September 13, 2017 -- Given its high sensitivity and negative predictive value, French researchers are promoting FDG-PET/CT for its ability to assess response to treatment and redirect therapy for patients with recurrent or progressive anal cancer, in a study published in the September issue of the Journal of Nuclear Medicine.  Discuss
AI algorithm can classify bone lesions on PET/CT images
September 7, 2017 -- An artificial intelligence (AI) algorithm can reliably classify benign and malignant bone lesions on F-18 sodium fluoride PET/CT images, showing promise for automating a time-consuming and subjective process for nuclear medicine physicians, according to a research team from the University of Wisconsin in Madison.  Discuss
Shorter PET/MRI scans feasible for pediatric cancer patients
August 23, 2017 -- Researchers at Stanford University have developed a single-session PET/MR imaging protocol that reduces scan times for cancer patients and increases accuracy for evaluating chemotherapy-induced brain, heart, and bone abnormalities, according to a study published online August 4 in Radiology.  Discuss
AI predicts dementia years before symptoms occur
August 22, 2017 -- An artificial intelligence (AI) algorithm can recognize the signatures of dementia on amyloid PET scans two years before the onset of symptoms, according to research published online recently in Neurobiology of Aging.  Discuss
Hybrid modalities disappoint in bone metastases accuracy
August 21, 2017 -- Despite the apparent technological advantages of SPECT/CT, PET/CT, and PET/MRI, the three hybrid modalities do not perform appreciably better than planar bone scintigraphy in detecting and diagnosing bone metastases, according to a study published online August 10 in the Journal of Nuclear Medicine.  Discuss
