New PET/CT tracer effectively targets blood clots
February 18, 2019 -- Researchers from South Korea and Germany are reporting excellent image quality and a high detection rate with PET/CT for acute venous thromboembolism thanks to a new radiotracer currently being developed, according to a paper published in the February issue of the Journal of Nuclear Medicine.  Discuss
New technique may top ultrasound for heart disease risk
February 12, 2019 -- A new imaging technique known as volumetric multispectral optoacoustic tomography provided better visualization of the carotid arteries than ultrasound did in a new study, published online February 12 in Radiology. It may help advance the noninvasive assessment of cardiovascular disease, according to the researchers.  Discuss
What is PET/MRI's value for cardiac sarcoidosis?
February 12, 2019 -- Much has been researched and written about the promise of PET/MRI. While the hybrid modality's range of clinical applications appears expansive, the authors of an editorial published online February 7 in the Journal of Nuclear Cardiology pose the opinion that it might be time to pump the brakes on wider use of PET/MRI, at least in cases of cardiac sarcoidosis.  Discuss
PET, AI show women's brains age differently than men's
February 7, 2019 -- Are women's brains really that much different from men's? In a word, yes. A machine-learning algorithm applied to data from multiparametric PET brain scans showed that women's brains are more "youthful" than those of men of the same age, according to a study published February 4 in the Proceedings of the National Academy of Sciences.  Discuss
Carbon-11 PET detects brain inflammation after Lyme disease
February 6, 2019 -- Researchers at Johns Hopkins Medicine have developed a PET imaging technique using a carbon-11-based radiotracer that confirmed an association between post-treatment Lyme disease syndrome and widespread inflammation in the brain.  Discuss
PET's view of tau could explain women's early dementia
February 5, 2019 -- Flortaucipir-PET scans have revealed increased levels of tau tangles in a key brain region in women, which could explain why they develop Alzheimer's disease-related dementia earlier than men and experience faster cognitive decline, according to a study published online February 4 in JAMA Neurology.  Discuss
SNMMI, ACNM oppose relaxing radiopharma user rules
January 31, 2019 -- The Society of Nuclear Medicine and Molecular Imaging (SNMMI) and the American College of Nuclear Medicine (ACNM) have submitted a joint statement opposing any changes in the U.S. Nuclear Regulatory Commission's training and experience requirements for healthcare personnel to administer radiopharmaceuticals.  Discuss
FET-PET adds 'relevant' info to pediatric cancer cases
January 30, 2019 -- Thanks to its high specificity, fluoroethyl-tyrosine (FET)-PET can help confirm the success of surgical procedures performed on pediatric patients with brain and spinal cord tumors to ensure that no residual tumor is left behind, according to a study published online January 25 in the Journal of Nuclear Medicine.  Discuss
United Imaging gets FDA nod for total-body PET/CT unit
January 22, 2019 -- Shanghai-based United Imaging Healthcare said it has received U.S. Food and Drug Administration (FDA) clearance for uExplorer, a total-body PET/CT scanner developed in collaboration with researchers from the University of California, Davis.  Discuss
How medical imaging can accelerate drug development
January 22, 2019 -- It can take 15 years to get a drug candidate from the lab to approval. Could medical imaging speed up that process? Olga Kubassova, PhD, of Image Analysis Group explains how imaging modalities such as MRI, CT, and PET are helping to track biomarkers in clinical studies, potentially bringing lifesaving therapies to patients more quickly.  Discuss
