October 30, 2020 -- A new analysis of imaging utilization during the COVID-19 pandemic demonstrates the outbreak's more severe impact on people of color and those of lower socioeconomic status, according to research published online ahead of print on October 29 in the Journal of the American College of Radiology.  Discuss
AI can identify sarcopenia in glioblastoma patients
October 30, 2020 -- An artificial intelligence (AI) algorithm can identify sarcopenia on routine brain MRI scans of patients with glioblastoma, enabling predictions of how long the patient might survive this aggressive cancer, researchers will report at next week's National Cancer Research Institute Virtual Showcase in the U.K.  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
GBCAs for cardiac MRI carry low allergic reaction risk
October 29, 2020 -- Using gadolinium-based contrast agents (GBCAs) for cardiac MRI carries a risk of less than 1% for allergic reactions -- although macrocyclic GBCAs do appear to be safer than linear ones, according to a study published October 29 in Radiology: Cardiothoracic Imaging.  Discuss
CTA spots COVID-19 in stroke patients
October 29, 2020 -- Scanning acute ischemic stroke patients with CT angiography (CTA) helps determine if they have COVID-19 faster than waiting for results from a nasal swab, say researchers in a study published October 29 in Stroke. The findings add to the debate over the best time to use CT during COVID-19.  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
Should genetic testing for breast cancer stop at 65?
October 27, 2020 -- Genetics still play a crucial role in whether women over the age of 65 develop breast cancer, according to new research to be presented at the American Society of Human Genetics 2020 meeting, taking place virtually October 27-30.  Discuss
