Can PET/MRI correlate tau with first responders' cognitive issues?
PET/MR images of tau deposits among emergency responders on 9/11 are concerning, but they fall short of a definitive link to dementia, according to research presented at the Society of Nuclear Medicine and Molecular Imaging's annual meeting in Vancouver, Canada.

PET shows aerobic exercise has little effect on amyloid
While aerobic exercise is good for the cardiovascular system, PET images show a weekly regimen of this activity does nothing to change the status of beta-amyloid buildup in older adults with elevated levels of the marker for Alzheimer's disease, according to a study published online January 14 in PLOS One.

PET/CT guidance offers valuable approach to lung biopsies
One optimum way to reduce inconclusive lung biopsy results and better detect malignancies is to use FDG-PET/CT for the image-guided procedure. Researchers from Brazil found that PET/CT had advantages over conventional CT guidance.

FDA makes history with approval of Ga-68 PSMA-11 PET
The U.S. Food and Drug Administration's (FDA) recent approval of a PET radiotracer that targets lesions positive for prostate-specific membrane antigen (PSMA) is not only a "quantum leap" for the diagnosis of prostate cancer in men but also sets a precedent for academic research.

PET ties coronary blood flow to future adverse events
Using PET perfusion to gauge cardiac blood flow capacity, researchers have found that severely reduced coronary flow reserve is a key contributor to a greater risk of a major adverse cardiac event and death, according to a study published online November 18 in Cardiovascular Imaging.
