PET links poor air quality to presence of amyloid plaque
December 4, 2020 -- PET scans of older Americans have revealed a potential link between the quality of air they breathe and the presence of brain plaque linked to Alzheimer's disease, according to a study published online November 30 in JAMA Neurology.  Discuss
PET ties coronary blood flow to future adverse events
November 20, 2020 -- 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.  Discuss
Tau Alzheimer's blood test gives PET a run for its money
November 10, 2020 -- Blood tests that detect a biomarker for abnormal tau metabolism in the brain were able to detect pathology earlier than PET scans in patients with preclinical Alzheimer's disease in a study reported online November 9 in JAMA Neurology.  Discuss
Coding and documentation for Y-90 radioembolization
November 9, 2020 -- The treatment of liver tumors using yttrium-90 (Y-90) radioembolization brings unusual challenges for interventional radiologists. Erin Stephens of Healthcare Administrative Partners describes how to overcome them.  Discuss
PET/CT with Ga-68 tracer better for cancer patients
November 2, 2020 -- By attaching gallium-68 (Ga-68) to a fibroblast activation protein molecule inhibitor, German researchers have achieved greater accuracy with PET/CT in staging patients with pancreatic ductal adenocarcinoma, according to a study published online October 23 in the Journal of Nuclear Medicine.  Discuss
Emerging PET tracer excels at tau pathology, differentiates dementias
October 29, 2020 -- A new PET radiotracer for tau pathologies is showing promise for helping diagnose and differentiate Alzheimer's disease from a wide range of other dementia disorders. Researchers detailed their early experiences in animal and patient studies in Neuron online October 29.  Discuss
Use F-18 fluciclovine PET/MRI to stage prostate cancer
October 28, 2020 -- PET/MRI with the F-18 fluciclovine radiotracer shows promise for initial staging of high-risk prostate cancer and for evaluating response to androgen deprivation therapy, according to a pilot study published online October 14 in the American Journal of Roentgenology.  Discuss
PSMA-PET reveals new salivary glands
October 28, 2020 -- Imaging with the use of prostate-specific membrane antigen (PSMA) has led to the discovery of a pair of salivary glands, found tucked away inside the skull where the nasal cavity and throat meet. The findings were published recently in Radiotherapy & Oncology.  Discuss
PET with Axumin boosts prostate cancer outcomes
October 27, 2020 -- Patients with recurrent prostate cancer had better outcomes when PET with the Axumin radiopharmaceutical was part of the imaging package guiding their radiation therapy, according to a study presented on October 26 at the American Society for Radiation Oncology annual meeting.  Discuss
Radiomics can aid management of lung cancer patients
October 26, 2020 -- Researchers from the H. Lee Moffitt Cancer Center and Research Institute in Tampa, FL, have reported that CT radiomics features can help predict tumor behavior in screening-detected lung cancer. They've also found that PET/CT radiomics shows promise for guiding non-small cell lung cancer treatment decisions.  Discuss
