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
AI aids detection of metastasis on bone scintigraphy
October 13, 2020 -- An artificial intelligence (AI) model was able to help nuclear medicine physicians improve their performance in diagnosing bone metastases on bone scintigraphy exams in patients with breast, lung, prostate, or other cancers, according to research published online October 12 in Scientific Reports.  Discuss
