PET identifies tau's origin in Alzheimer's disease
January 21, 2021 -- An automated PET image analysis method can track the development of tau protein clumps in the brains of people with Alzheimer's disease, revealing an important clue in how the devastating disease could potentially be treated, according to research published online January 20 in Science Translational Medicine.  Discuss
SNMMI urges fast-track review of Technegas for V/Q scans
January 21, 2021 -- The Society of Nuclear Medicine and Molecular Imaging (SNMMI) has sent a letter to the U.S. Food and Drug Administration (FDA) urging the agency to begin a fast-track review of the Technegas agent for nuclear medicine ventilation/perfusion (V/Q) lung scans.  Discuss
PET shows aerobic exercise has little effect on amyloid
January 20, 2021 -- 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.  Discuss
Report charts 80% drop in cardiac SPECT during COVID-19
January 15, 2021 -- A hospital in Alabama saw an 80% drop in the volume of SPECT myocardial perfusion imaging studies during the peak of the COVID-19 pandemic in spring 2020 as patients postponed nonessential procedures.  Discuss
PET/CT guidance offers valuable approach to lung biopsies
January 13, 2021 -- 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.  Discuss
Could AI lower malpractice risk for physicians?
January 12, 2021 -- Although some legal scholars believe that liability concerns could hinder adoption of artificial intelligence (AI) software in personalized medicine, a new study published in the Journal of Nuclear Medicine found that physicians who follow the technology's advice may actually be shielded from malpractice liability.  Discuss
Is there a place for whole-body cancer screening?
January 12, 2021 -- A whole-body imaging cancer screening program could be an effective way to detect early-stage cancer among a motivated screening population, according to a study from Japan published January 1 in the Journal of the American College of Radiology.  Discuss
Copper radiotracers ID tumors, improve survival
December 21, 2020 -- Two copper radionuclides that target the somatostatin receptor overexpressed in neuroendocrine tumors can not only identify tumors but also improve survival, according to new research published in the December issue of the Journal of Nuclear Medicine.  Discuss
FDA makes history with approval of Ga-68 PSMA-11 PET
December 18, 2020 -- 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.  Discuss
PET is useful modality in patients with lymphomas
December 16, 2020 -- PET imaging can permit more accurate staging in lymphomas, guide treatment, and make a difference in overall patient survival. That's the message from a discussion about imaging in patients with lymphomas at the virtual annual meeting of the American Society of Hematology in early December.  Discuss
