FET-PET can be useful for glioma evaluations
September 18, 2019 -- When glioma results are inconclusive on MRI, clinicians should consider fluoroethyl-tyrosine (FET)-PET for more definitive results and to differentiate between tumor progression and treatment improvement, according to a study published online September 13 in the Journal of Nuclear Medicine.  Discuss
PET, MRI link amyloid plaque with swift decline
September 12, 2019 -- Patients whose PET and MR images show beta-amyloid plaque accumulation in the brain experience a significantly faster path toward dementia than people with vascular dementia and no plaque deposits, according to a study published online September 11 in Neurology.  Discuss
Ga-68 PSMA PET/MRI, mpMRI work for prostate cancer analysis
September 12, 2019 -- Prostate cancer patients at intermediate or high risk of advanced disease can benefit from either gallium-68 (Ga-68) prostate-specific membrane antigen (PSMA) PET/MRI or multiparametric MRI (mpMRI) alone to diagnose specific features of their disease, according to a study published September 10 in Radiology.  Discuss
Flortaucipir-PET shows tau accumulation after one TBI
September 6, 2019 -- A single moderate-to-severe traumatic brain injury (TBI) can trigger signs of accumulation of neurodegenerative tau protein on dynamic flortaucipir-PET images and lead to cognitive decline, according to a study published September 4 in Science Transitional Medicine.  Discuss
NaF-PET/CT does well in detecting prostate metastases
September 6, 2019 -- Nuclear medicine physicians showed high accuracy and consistency when reading sodium fluoride (NaF)-PET/CT scans of patients with prostate cancer metastases in a new study, published online September 3 in the Journal of Nuclear Medicine.  Discuss
Cancer deaths eclipse heart disease in developed world
September 4, 2019 -- Cancer is now the leading cause of death in high-income countries, with twice as many people dying from cancer than heart disease in these nations. Heart disease continues to be the main cause of death in less prosperous countries, according to data presented at this week's European Society of Cardiology meeting in Paris.  Discuss
FDG-PET/CT helps predict tuberculosis relapse
August 28, 2019 -- When FDG-PET/CT scans reveal lingering metabolic activity in the lungs of tuberculosis (TB) patients after treatment, approximately 10% of them will experience a relapse of the disease within six months, according to a study published online August 26 in the Journal of Nuclear Medicine.  Discuss
Which nuclear modality has the lowest dose for CHD?
August 21, 2019 -- Reducing radiation exposure from myocardial perfusion imaging is a key priority, especially for congenital heart disease (CHD) patients who face repetitive scanning. Which nuclear imaging modality and radiotracer are best for this task is the subject of a study published August 12 in the Journal of Nuclear Cardiology.  Discuss
NRC proposes changes to rules on radiotracer patients
August 15, 2019 -- The U.S. Nuclear Regulatory Commission (NRC) is proposing several updates in its regulatory guide on how best to handle patients who receive radioactive materials as part of their imaging scans.  Discuss
Study: FDG-PET reigns supreme for assessing Alzheimer's
August 9, 2019 -- FDG-PET is superior to amyloid PET imaging with the radiopharmaceutical florbetapir for assessing cognitive decline in patients with Alzheimer's disease or mild cognitive impairment, according to research published in the August issue of the Journal of Alzheimer's Disease.  Discuss
