Radiation events prompt FDA notice on Rb-82 generators
May 1, 2019 -- The U.S. Food and Drug Administration (FDA) has bolstered its requirement for safety labels on rubidium-82 (Rb-82) generators for PET studies. The action follows reports of a "serious incident" of excess radiation exposure to patients caused by what the FDA called "user error."  Discuss
NIH awards grant to develop PET plaque tracers
May 1, 2019 -- The U.S. National Institutes of Health (NIH) has awarded a $5.1 million grant to researchers at Mallinckrodt Institute of Radiology to develop PET-based imaging tools to distinguish vulnerable plaque in the body.
Would high amyloid level spur physician-assisted death?
April 30, 2019 -- If physician-assisted death were legal, how many people with elevated beta-amyloid levels would opt for it if they experienced a cognitive decline due to Alzheimer's disease? Not that many, according to a research letter published online April 29 in JAMA Neurology.  Discuss
ASTRO: Prior authorization delays radiation treatment
April 26, 2019 -- Requiring radiation oncologists to obtain prior authorization from third-party entities before starting cancer therapy is causing unnecessary delays and potentially life-threatening outcomes for patients, according to a survey released April 25 from the American Society for Radiation Oncology (ASTRO).  Discuss
DeepPET network smooths out PET image quality
April 25, 2019 -- Researchers from Memorial Sloan Kettering Cancer Center in New York City have developed a deep-learning network called DeepPET to generate high-quality PET images more than 100 times faster than currently possible, according to a study published in the May issue of Medical Image Analysis.  Discuss
MRI shows obesity can influence brain volume
April 23, 2019 -- Obesity can change more than the size of your waistline. In a new study published online April 23 in Radiology, Dutch researchers used MR images to link greater levels of body fat to changes in the brain's form and structure, particularly with smaller volumes of gray matter.  Discuss
Could Ga-68 PSMA PET become essential for prostate cancer?
April 23, 2019 -- Coupling the radiopharmaceutical gallium-68 (Ga-68) prostate-specific membrane antigen (PSMA) with PET/CT or PET/MRI has been a boon for prostate cancer imaging. But clinicians still need to be aware of some inherent shortcomings with the radiopharmaceutical, according to a research review published online April 12 in Urology.  Discuss
MRE could measure brain function dramatically faster
April 17, 2019 -- U.S. and European researchers could be on the brink of advancing the measurements of brain function through a MRI brain scan to milliseconds with an MR elastography technique, according to a preclinical study published online April 17 in Science Advances.  Discuss
Ga-68 PSMA PET/CT for prostate wins Australian favor
April 17, 2019 -- When a prostate cancer staging exam is needed, clinicians at one Australian hospital are overwhelmingly choosing PET/CT with the radiopharmaceutical gallium-68 (Ga-68) prostate-specific membrane antigen (PSMA), according to a study published online April 11 in the Journal of Medical Imaging and Radiation Oncology.  Discuss
Flortaucipir-PET shows promise for detecting CTE
April 12, 2019 -- Flortaucipir-PET scans revealed high amounts of tau protein in brain regions associated with chronic traumatic encephalopathy (CTE) in former professional football players, potentially enabling this disease to one day be diagnosed before death, according to new research in the New England Journal of Medicine.  Discuss
